Go Code Review Comments

This page collects common comments made during reviews of Go code, so that a single detailed explanation can be referred to by shorthands. This is a laundry list of common mistakes, not a style guide.

You can view this as a supplement to http://golang.org/doc/effective_go.html.

Please discuss changes before editing this page, even minor ones. Many people have opinions and this is not the place for edit wars.
