The changes between (equivalent, and reviewed) go/types/decl.go
and decl.go can be seen by comparing patchset 1 and 2. The actual
changes are removing the "// UNREVIEWED" marker and a minor comment
update.
The primary differences to go/types/decl.go are:
- use of syntax rather than go/ast package
- use of error_ objects to collect follow-on error info
- use of check.conf.Trace rather than global trace flag
- more aggressively marking variables as used in the presence errors
- not using a walkDecl abstraction for const/var/type declarations
