If we have 

expr = Num(object value, num_type type)
num_type = Int | Long | Float | Complex

Then I can parse the string and create a num passing the PyObject *
and setting the appropriate type flag.  I could also handle separate
IntNum, LongNum, etc. ctors, but that seems like more nodes that we
really need.

If the Num node(s) need to have the type specified, that I'd like it
to take an object not a string.
