Except that it has a signature, isClassMethod, etc.  It's not a 
perfectly normal object, it's a selector instance.  One of the big 
"selling points" of ObjC is that you can pretty much translate ObjC 
code to Python, this is a stumbling block I think we should work 
around.  With the "algorithm" I posted earlier, using these special 
"classMethod / instanceMethod" accessors should never really be 
necessary, except in rare instances where you are doing 
SomeClass.someInstanceMethod(instance, ...) with varargs or something.
