Your question might not seem so silly (sorry) if we can see the problem you are trying to solve. --Reply-- I'm not actually trying to solve a problem, just understand a behavior. Because I'm replacing portions of IronPython to allow me to interrupt a script at any point (and save local variables and the instruction pointer), I have to reimplement code. Originally I had classes running the code under the class scope on every instance (I thought it was like C# where class assignments are basically added to all constructors); then it was noticed that in instances where the class code ran a function this was a variation in the behavior of IronPython /w Fibers vs. Interuptable IronPython. I realized my mistake, fixed it, and the unit test case included not only assigning variables and running functions (which was used in the python scripts we've already made), but assigning functions--both to the class and the instance. Again it had a variation (Our Interruptable didn't see the extra variable, IronPython complained), as I was assuming that any assignment of a function would assign the function type instead of a bound/unbound method on class types. After all, changing a variable on the class only changed the referance, not the type. This lead to the E-mail, as I didn't understand what exactly was going on here. It seems to be somewhat inconsistent. So I don't actually have a problem needing a solution, just a "Why is it that way?" sort of question. At the moment, I'm having difficulty visualizing a real world scenario where this capability would be useful; it just happened to be a part of the testing scenarios to ensure consistent behavior. If it were like an event, would it not be preferable to be able to have a "default event" that can be overriden with an "instance event"? Otherwise, why have instance functions at all?
