I guess nobody has tried to create frozenset instances from C code before. Almost everyone uses set anyway. What are you trying to do?

I'm looking at building a "frozenset" instance as a return value from a C function, and the C API seems ridiculously clumsy. Maybe I'm misunderstanding it. Apparently, I need to create a list object, then pass that to PyFrozenSetNew(), then decref the list object.

Is that correct? What I'd like is something more like PyFrozenSetNEW(int) => PySetObject * PyFrozenSetSETITEM(s, i, v) Any idea why these aren't part of the API? Bill
