[issue17577] Add lookahead/peek wrapper to itertools

[Raymond Hettinger]

Raymond Hettinger added the comment:

Based on previous discussions on the subject, I'm disinclined to accept a lookahead tool for the itertools module.  Adding a recipe using tee() may be reasonable though.

I'll mark this a low priority and will come back an give in more consideration at some point.
