I really like this idea.  If a patch appeared on SF soon, do you think
2.3 could include a warning for code that violates the rule?

If so, how about also including a flag to allowed optimizations based on
the rule?  For example, I think we could have the equivalent of
LOAD_FAST for builtin names.  Implementing the optimizations could be a
bit of work, especially with the existing compiler, but I think the
warning should be fairly easy.
