Re: Number classes

For CPython, I've got a single routine called parsenumber().  It
converts a string to a PyObject * of the appropriate type.  So for my
code, the only way I could find out if I've got an int vs. a complex
is to parse it and check the return type.  But once I've got the
PyObject *, there's no need to pass a string to ctor.

Is the 'object' type your thinking of for ASDL the generic object type
of the Python implementation?  So I would actually pass the ComplexNum
ctor a PyObject *?

For the code generator, the various number objects are all treated the
same way once they're parsed.  (Unless the compiler was doing some
constant folding, I suppose.)  If there's no difference to the way the
numbers are handled, it would be better to mark a generic Num type
with some flags or attributes that provide the extra info.
