It may be possible to go into dark places to discover what code first imported a module, but its not possible to discover what code does subsequent imports-- and in either case, this is /not/ something that has any sort of elegance to it. Its deeply hackish. If you want a piece of code to have a variable number of differing behaviors, that's something you can handle in many elegant ways. That's something inheritance is good for, with a core default behavior represented in one class and more specialized behavior represented in sub-classes. But either way, you have to tell it which class to create at the moment, which entails passing in a parameter explicitly activating one or the other. This is a good thing. Don't try to get around it. --S
