Hmm. I think this limits interoperation with C libraries and prototyping
C code.
This is mostly a red-herring. flufl.enum values are C-level int compatible
without actually *being* ints.
E.g.
static PyObject *
intcompat_printint(PyObject *self, PyObject *args)
{
 int value;
 if (!PyArg_ParseTuple(args, "i", &value))
 return NULL;
 printf("and the value is: %d\n", value);
 Py_RETURN_NONE;
}
from _intcompat import *
printint(7)
and the value is: 7
from flufl.enum import make
Colors = make('Colors', 'red green blue'.split())
printint(Colors.green)
and the value is: 2
Okay, that's pretty cool.
I would still like the int subclass, though, as it would be an aid to me on the 
Python side.
