Russ Cox 917aa35f8f implications of stricter type equality:
if both types are named, they must be
the same type (arising from the same
declaration).

also leave type alone after conversion failure,

Russ Cox 9cba9c8890 6l: eliminate dead code, not just the symbols
editing the firstp list was ineffective,
because follow rebuilds it from the textp list.

the symbols for dead code were being dropped
from the binary but the code was all still there.

text for fmt.Printf("hello, world\n") drops
from 143945 to 128650.

David Symonds 2f284948af Remake exvar package to be more Go-ish.
It now exports a Var interface (anyone can export their own custom var types now), so users need to create and manage their own vars and mark them as exportable via the Publish function. They are exposed via /debug/vars.

Kai Backman eac5db7f4c Copied 8g/6g into 5g. Used sharp tools to coax a .5 file out
of 5g. 5l balks at the output and running 5g with -S shows
the true extent of the disaster. Still, better than
yesterday. Maybe.

Tested on the canonical:

package main
func main() {
}
