Robert Griesemer	e1d6b3c98d	go/ast: fix ast.Walk ... - change Walk signature to use an ast.Node instead of interface{} - add Pos functions to a couple of ast types to make them proper nodes - explicit nil checks where a node can be nil; incorrect ASTs cause Walk to crash For now ast.Walk is exercised extensively as part of godoc's indexer; so we have some confidence in its correctness. But this needs a test, eventually. Fixes #1326. R=rsc, r CC=golang-dev https://golang.org/cl/3481043	2010-12-09 10:22:01 -08:00
