It would seem even easier (and a lot faster) to use an array to go from C enum --> some object, which could as well be an interned string as anything else.

Have you actually looked at the code? How could it be faster than

PyObject* ast2obj_boolop(boolop_ty o) { switch(o) { case And: Py_INCREF(And_singleton); return And_singleton; case Or: Py_INCREF(Or_singleton); return Or_singleton; } return NULL; /* cannot happen */ }

Not sure what interned strings have to do with it.
