Because of how the compiler internally represents variable references,
it sometimes gets position information incorrectly for them. The
codelens test hits this issue because for
var x string
fmt.Println(x)
the diagnostic about "x" escaping to heap (which actually refers to
the implicit conversion to "interface{}" type) should be rightly
reported at the "x" identifier within the call arguments list.
However, due to the aforementioned compiler bug, historically we
reported the diagnostic at the "(" token instead.
In -G=3 mode, the compiler (correctly) report the diagnostic at "x"
instead; but with GOEXPERIMENT=unified, the compiler intentionally
matches the original -G=0 behavior and continues reporting at "("
instead.
This CL avoids the issue entirely by changing the line to
"fmt.Println(42)", which avoids the issue because the compiler always
correctly prints the diagnostic then at "42".

Go Tools
This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc and vet for example, are included in binary Go
distributions.
Others, including the Go guru and the test coverage tool, can be fetched with
go get.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
Download/Install
The easiest way to install is to run go get -u golang.org/x/tools/.... You can
also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
JS/CSS Formatting
This repository uses prettier to format JS and CSS files.
The version of prettier used is 1.18.2.
It is encouraged that all JS and CSS code be run through this before submitting a change. However, it is not a strict requirement enforced by CI.
Report Issues / Send Patches
This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.
The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with "x/tools/(your subdir):" in the subject line, so it is easy to find.
