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?
