What is the issue?
The 'tee' object doesn't have a "send" method. (This is true for all of the itertools iterators, I believe). The request is misguided though - the itertools module is designed to operate on output-only iterators, not on generators that expect input via send(). Because the output values might depend on the values sent, then it makes no sense to cache them (or do most of the other things itertools does). The relevant functionality would actually make the most sense as a fork() method on generators, but PEP 342 was trying to be fairly minimalist.
