I don't know enough about the issues to have an opinion on the proposal as a whole, but the foo.iterkeys() -> six.iterkeys(foo) transformation strikes me as exactly the kind of change that can be easily and accurately automated (as in modernize etc.). I assume Glyph et al have considered this option -- do you know why it was rejected? -- Nathaniel J.
