[Python-Dev] Re: Sets: elt in dict, lst.include

With all this confusion about how to actually write the
iteration on dictionary items, wouldn't it make more sense
to implement an extension module which then provides a __getitem__
style iterator for dictionaries by interfacing to PyDict_Next() ?
The module could have three different iterators:
1. iterate over items
2. ... over keys
3. ... over values
The reasoning behind this is that the __getitem__ interface
is well established and this doesn't introduce any new
syntax while still providing speed and flexibility.
