[Python-Dev] Comparison speed (original) (raw)

Anybody care to take a stab at making the new richcmp and/or coerce code ugly again?

When stepping through the code, I also missed support for the relationship between identity and equality. E.g. in PyObject_RichCompare, I'd expect

if (v == w) { switch (op) case Py_EQ:case Py_LE:case Py_GE: Py_INCREF(Py_True); return Py_True; case Py_NE:case Py_LT:case Py_GT: Py_INCREF(Py_False); return Py_False; } }

That would not help in your case, of course. I don't even know how frequent comparing identical objects is in real life - but this is something that PyObject_Compare has that PyObject_RichCompare currently doesn't.
