Actually, as I read the code, that would be:
with decimal.getcontext().get_manager() as ctx:
Which is still horrible, but unfortunately Guido has already pronounced
that __context__ must be removed from PEP 343, which is what caused this
abomination to come about.
The PEP currently offers the idea of a 'localcontext()' API that provides a
nicer spelling, but it appears nobody implemented it.
