[Python-Dev] Allowing slicing of iterators

I just wrote a new C API function (PyItem_GetItem) that supports slicing for
arbitrary iterators. A patch for current CVS is at http://www.python.org/sf/1108272
For simple indices it does the iteration manually, and for extended slices it
returns an itertools.islice object.
As a trivial example, here's how to skip the head of a zero-numbered list:
for i, item in enumerate("ABCDEF")[1:]:
print i, item
Is this idea a non-starter, or should I spend my holiday on Wednesday finishing
it off and writing the documentation and tests for it?
Regards,
Nick.
