Incidentally, I'd give my right arm for a non-mutable dictionary.  Why?
Because certain methods (in the new module, plus the exec keyword, as classic
examples) won't let me pass anything but a "true" dictionary in as namespace
- and I want to run methods in a namespace they cannot modify.

Would be even better if you could use user classes in those places, but I'd
happily settle for non-mutable dictionaries ;)
