Cool!

I will build upon this code.
Thanks for your help

Hi
I would like to check if an index is in a slice or not without
iterating over the slice.
Something like:
>>> isinslice(36, slice(None, 34, -1))
True
I would like to use the batteries if possible.
However, I looked in the docs, pypi and in Usenet without luck.
Does anyone have a solution?
