Oops, you're right. I should be careful not to mix up my Germans;-)
I am more in favour of exposing the pickle reduce API through "O@", that is have PyArgTuple_Parse() call the .__reduce__() method of the object. This will then return (factory, state_tuple) and these could then be exposed to the C function via two PyObject*.
You've suggested this before, but at that time I ignored it because it made absolutely no sense to me. "pickle" triggers one set of ideas for me, "reduce" triggers a different set, "factory function" yet another different set. None of these sets of ideas have the least resemblance to what I'm trying to do:-) I gave a fairly complete example (using calldll from Python to wrap a function that returns a Mac WindowObject) last week, could you explain how you would implement this with pickle, reduce and factory functions? -- - Jack Jansen <Jack.Jansen@oratrix.com> http://www.cwi.nl/~jack - - If I can't dance I don't want to be part of your revolution -- Emma Goldman -
