Are float("inf") and float("nan") supported everywhere? I don't have ready
access to a Windows machine, but on the couple Linux and MacOS machines
at-hand they are. As a starting point can it be agreed on whether they
should be supported? (There is a unique IEEE-754 representation for both
values, right? Should we try and support any other floating point format?)
If so, the float("1e10000") == float("inf") in all cases, right? If not,
then Python's lexer should be trained to know what out-of-range floats are
and complain when it encounters them. In either case, we should then know
how to fix marshal.loads (and probably pickle.loads).
That seems like it would be a start in the right direction.
