I have read most of the PEP 572 related threads, but I don't think I've seen this idea. As many other people mentioned, Python already allows a trick to introduce local bindings in generator expressions and list comprehensions. This can be achieved by adding a "for var in [<expr>]" clause. I propose to make "for var = <expr>" have the same effect as "for var in [<expr>]".
It was discussed before (at least in the context of comprehensions), and was rejected because in some other popular languages `for var = <expr>` is the same as `for var in <expr>` in Python.
