The float types already emit string-representation of nan's and inf's
but doesn't know how to parse them back. This parsing step should be
trivial to implement.
I cannot see any cross-platform issues with this. If the floats aren't
binary compatible across platforms we'll have to face these issues
regardless of the string representation (I think they are, except for
If cross-platform issues includes string representation from other
sources than python 3.0, things get trickier. I think that python
should handle it's own string representation, others could always be
handled with sub-classing. At a minimum "float(str(nan))==nan" should
evaluate as True.
