Remove the __iter__ method from the UserDict class -- it can silently
break old code (in extreme cases). See SF bug #448153.
Add a new subclass IterableUserDict that has the __iter__ method.
Note that for new projects, unless backwards compatibility with
pre-2.2 Python is required, subclassing 'dictionary' is recommended;
UserDict might become deprecated.
