Thanks for writing that up. I like the idea in general.

As for input from the "major Python implementations", we currently do 
similar things internally in Cython for optimisation purposes, so a 
syntactic 'where' clause with expression-local scope would be trivial to 
implement on our side as most of the infrastructure is there anyway.
