Although one may argue that they should be legal, gc (at least)
disallows byte order marks that are not the first code point
in the file. Added a sentence to the "Implementation restriction"
clause in the "Source code representation" section to document
this better.
Lifting this restriction (again - the rule has changed at least

we later decide yet again to fiddle the rules about these little

Back in the day, before the Go 1.0 release, $GOROOT was mandatory for building from source. Fast forward to now and $GOPATH is mandatory and $GOROOT is optional, and mainly used by those who use the binary distribution in uncommon places.
For example, most novices at least know about `sudo` as they would have used it to install the binary tarball into /usr/local. It is logical they would use the `sudo` hammer to `go get` other Go packages when faced with a permission error talking about the path they just had to use `sudo` on last time.
Even if they had read the documentation and set $GOPATH, go get will not work as expected as `sudo` masks most environment variables.
llucky(~) % ~/go/bin/go env | grep GOPATH
GOPATH="/home/dfc"
lucky(~) % sudo ~/go/bin/go env | grep GOPATH
GOPATH=""
This CL therefore proposes to remove support for using `go get` to download source into $GOROOT.
This CL also proposes an error when GOPATH=$GOROOT, as this is another place where new Go users can get stuck.

This CL adds a flag parser that matches the semantics of Go's
package flag. It also changes the linkers and compilers to use
the new flag parser.
Command lines that used to work, like
8c -FVw
6c -Dfoo
5g -I/foo/bar
now need to be split into separate arguments:
8c -F -V -w
6c -D foo
5g -I /foo/bar
The new spacing will work with both old and new tools.
The new parser also allows = for arguments, as in
6c -D=foo
5g -I=/foo/bar
but that syntax will not work with the old tools.
In addition to matching standard Go binary flag parsing,
the new flag parser generates more detailed usage messages
and opens the door to long flag names.
The recently added gc flag -= has been renamed -complete.

The Plan 9 symbol table format defines big-endian symbol values
for portability, but we want to be able to generate an ELF object file
and let the host linker link it, as part of the solution to issue 4069.
The symbol table itself, since it is loaded into memory at run time,
must be filled in by the final host linker, using relocation directives
to set the symbol values. On a little-endian machine, the linker will
only fill in little-endian values during relocation, so we are forced
to use little-endian symbol values.
To preserve most of the original portability of the symbol table
format, we make the table itself say whether it uses big- or
little-endian values. If the table begins with the magic sequence
fe ff ff ff 00 00
then the actual table begins after those six bytes and contains
little-endian symbol values. Otherwise, the table is in the original
format and contains big-endian symbol values. The magic sequence
looks like an "end of table" entry (the fifth byte is zero), so legacy
readers will see a little-endian table as an empty table.
All the gc architectures are little-endian today, so the practical
effect of this CL is to make all the generated tables little-endian,
but if a big-endian system comes along, ld will not generate
the magic sequence, and the various readers will fall back to the
original big-endian interpretation.

This is an attempt at making the interaction between
these three constructs clearer. Specifically:
- return statements terminate a function, execute deferred
functions, return to the caller, and then execution
continues after the call
- panic calls terminate a function, execute deferred
functions, return to the caller, and then re-panic
- deferred functions are executed before a function _returns_
to its caller

deferred function is executed (when a function returns),
and when it is not (when a program exits).

- Define what it means for two identifiers to be unique.
- The current spec is incorrect about exported
identifiers: for instance, it excluded fields
of non-exported types of exported variables
from being exported. It is easier to leave
the detailed specification away and let the
rest of the spec govern access of exported
identifiers.
- The current spec is incorrect about qualified

When we first wrote the method set definition, we had long
discussions about whether method sets applied to all types
or just named types, and we (or at least I) concluded that it
didn't matter: the two were equivalent points of view, because
the only way to introduce a new method was to write a method
function, which requires a named receiver type.
However, the addition of embedded types changed this.
Embedding can introduce a method without writing an explicit
method function, as in:
var x struct {
sync.Mutex
}
var px *struct {
sync.Mutex
}
var _, _ sync.Locker = &x, px
The edits in this CL make clear that both &x and px satisfy
sync.Locker. Today, gccgo already works this way; 6g does not.

If a printer is configured with the SourcePos mode
set, it will emit //-line comments as necessary to
ensure that the result - if reparsed - reflects the
original source position information.
This change required a bit of reworking of the
output section in printer.go. Specifically:
- Introduced new Config mode 'SourcePos'.
- Introduced new position 'out' which tracks the
position of the generated output if it were read
in again. If there is a discrepancy between out
and the current AST/source position, a //line
comment is emitted to correct for it.
- Lazy emission of indentation so that //line
comments can be placed correctly. As a result,
the trimmer will have to do less work.
- Merged writeItem into writeString.
- Merged writeByteN into writeByte.
- Use a []byte instead of a byte.Buffer both in the
printer and in the trimmer (eliminates dependency).
Also: introduced explicit printer.Mode type (in
sync w/ parser.Mode, scanner.Mode, etc.)
Runs all tests. Applied gofmt to src, misc w/o changes.

Issue 2856 asks for a rename of a few methods to a
more idiomatic Go style. This is a very early API
that evolved organically throughout the years.
Together with the fact that ErrorVectors were embedded
in other data structures (e.g. Parser), just renaming
methods (e.g. GetError -> Error) would lead to undesired
behavior (e.g., Parser would act like an Error). Instead,
cleaned up API a bit more:
- removed ErrorVector in favor of ErrorList (already
present)
- simplified Scanner.Init by making the error handler a
function instead of requiring an ErrorHandler implementation
- adjusted helper functions accordingly
- updated Go 1 doc

Previously, a timeout (in int64 nanoseconds) applied to a granularity
even smaller than one operation: a 100 byte read with a 1 second timeout
could take 100 seconds, if the bytes all arrived on the network 1 second
apart. This was confusing.
Rather than making the timeout granularity be per-Read/Write,
this CL makes callers set an absolute deadline (in time.Time)
after which operations will fail. This makes it possible to
set deadlines at higher levels, without knowing exactly how
many read/write operations will happen in e.g. reading an HTTP

An experiment: allow structs to be copied even if they
contain unexported fields. This gives packages the
ability to return opaque values in their APIs, like reflect
does for reflect.Value but without the kludgy hacks reflect
resorts to.
In general, we trust programmers not to do silly things
like *x = *y on a package's struct pointers, just as we trust
programmers not to do unicode.Letter = unicode.Digit,
but packages that want a harder guarantee can introduce
an extra level of indirection, like in the changes to os.File
in this CL or by using an interface type.
All in one CL so that it can be rolled back more easily if
we decide this is a bad idea.

They should be of the form:
// Output of this function.
func ExampleFoo() {
fmt.Println("Output of this function.")
}
It also modifies godoc to read example code from _test.go files,
and include them in the HTML output with JavaScript-driven toggles.
It also implements testing of example functions with gotest.
The stdout/stderr is compared against the output comment on the
function.
This CL includes examples for the sort.Ints function and the
sort.SortInts type. After patching this CL in and re-building go/doc
and godoc, try
godoc -http=localhost:6060
and visit http://localhost:6060/pkg/sort/

-- removes Response.RequestMethod string
-- adds Response.Request *Request
-- removes the finalURL result parameter from client.Get()
-- adds a gofix rule for callers of http.Get which assign
the final url to the blank identifier; warning otherwise
Caller who did:
res, finalURL, err := http.Get(...)

res, err := http.Get(...)
if err != nil {

This CL proposes some subtle language changes
in an attempt to clarify the semantics of range
clauses and simplify uses of maps.
- nil maps behave like empty maps; but attempting
to set a value in a nil map causes a run-time panic
- nil channels are never ready for communication;
sending or reading from a nil channel blocks forever
- if there is only one index iteration variable in a
range clause and len(range expression) would be a constant,
the range expression is not evaluated.
(was discrepancy with len/cap before)
- the notion of what is a constant expression len(x)
for (pointer to) arrays x has been generalized and
simplified (can still be syntactically decided)
(before: more restrictive syntactic rule that was not
consistently implemented)

This change makes it legal to pass a struct value as receiver
outside the package declaring the struct even if the respective
struct type has non-exported fields.
This is a backwards-compatible language change motivated by the
fact that it is already possible to circumvent the assignment
restriction when calling methods through interfaces (see issue
1402).

Prior to this CL, there were two requirements about the
package name main.
1. The package that sits at the root of the import graph
(the one where program execution begins)
must be named main.
2. No other package in the program can be named main.
This CL only removes requirement #2, which can be done
without changing any other Go documentation.
The new wording and formatting is such that removing
requirement #1 can be done by deleting a single line,
but making that change is explicitly outside the scope
of this CL, because it would require changes to other
documentation at the same time.

These are syntactical changes to better reflect the communication
operator's new status in the language.
- sending to a channel is now done via a send statement
- there is no binary communication operation anymore which
leads to a reduction of the number of precedence levels
from 6 to 5 (yeah!)
- small semantic change: since a send operation is not part
of the expression syntax anymore, a <- send operator is
binding weaker than any other operator now
- receiving from a channel is done as before via the unary
receive expression
- communication clauses in select statement now can contain
send statements or receive expressions

The default float type is not very useful but for the most basic applications.
For instance, as it is now, using the math package requires conversions for float
variables (the arguments for math functions are usually float64). Typical real
applications tend to specify the floating point precision required.
This proposal removes the predeclared types float and complex. Variable declarations
without type specification but with constant floating point or complex initializer
expressions will assume the type float64 or complex128 respectively.
The predeclared function cmplx is renamed to complex.

Regular expressions may now be used in conjuction with full text
search. Godoc will show the first 10000 occurences in the source
code and highlight the respective text segments.
- added new flag -testDir to specify a small directory for testing
(fast index creation; default = "")
- use new FormatText function to format text and Go source
code in HTML, supporting multiple kinds of text selections
simulatenously); this replaces the uses of go/printer
Stylers
- for now removed currently unused mechanism for identifier-
specific JS popups (will come back in some form once we
have type or other useful information)
- various typo fixes and minor cleanups throughout
Missing:
