[Python-ideas] ChainMap as a context manager

How about adding the context manager protocol to collections.ChainMap,
as an in-place combination of new_child() and parents()? The effect
would simulate lexical scope using the with-statement.

Trivial to do customly but always nice when builtin or stdlib types
support the context manager protocol. :)
