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
