+Ordered comparisons between enumeration values are not supported. Enums are +not integers! 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
