[dmitshur] this helps me a ton right now because I'm currently specifying users by a
{ID uint64; Domain string} pair where ID == 0 means "no user", and I'm not in a position to easily change that... that decision was made long ago in a package I'm currently sharing between far too many other things (see https://godoc.org/github.com/shurcooL/users?importers)
