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.
Regards,
Martin
