This also allows passing a factory function instead of a class, BTW. I recently had the reverse case that a (stupidly implemented) extension module required a callback function and I wanted to pass a function wrapped in a wrapper object. That failed, because it specifically checked for the argument being a function, not just a callable object. I had to pull quite a number of tricks to reimplement the wrapper class as a function (thank god, it's Python!). Stefan -- http://mail.python.org/mailman/listinfo/python-list
