Oops, you're right. I should be careful not to mix up my Germans;-)

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?
