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

[M.-A. Lemburg]

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.
