Ok, I tested zope.schema in python 3.2.2 and there were some errors in
test_vocabulary.py that I fixed.

They were all related to the KeysView and ValuesView objects (being
returned by keys() and values() on an OrderedDict) not being indexable.

There is however still one more error when testing with Python 3.2.2,
but this is related to the IContextSourceBinder validation changes made
by rogerineichen.

First the error:

The vocabulary is of type SampleContextSourceBinder from test_choice.py,
which does implement IContextSourceBinder.

Looking at it in pdb:

Just to double-check, I looked at this vocabulary in Python 2.7:

There it *does* provide IContextSourceBinder.

Any ideas why this vocabulary doesn't provide it in Python 3?
