"Why in the world would you want callable modules you ask?" I don't have a real need, but I often see the line blurred between package, module, and class.
Please don't try to blur the line between module and class. This has been proposed many times, and the net result IMO is always more confusion and no more power. This is also why in 2.3, modules are no longer subclassable. If you really need to have a module that has behavior beyond what a module can offer, the officially sanctioned way is to stick an instance of a class in sys.modules[__name__] from inside the module's code. (I would explain more about *why* I think it's a really bad idea, but I'm officially on vacation.) --Guido van Rossum (home page: http://www.python.org/~guido/)
