One of the things I find annoying about Python is that when you make a change to a method definition that change is not reflected in existing instances of a class (because you're really defining a new class when you reload a class definition, not actually redefining it). So I came up with this programming style:
def defmethod(cls): return lambda (func): type.__setattr__(cls, func.func_name, func) class c1(object): pass @defmethod(c1) def m1(self, x): ... Now if you redefine m1, existing instances of c1 will see the change. My question is: is there a reason not to do this? Does it screw something up behind the scenes? Is it unpythonic? Why isn't this standard operating procedure? rg -- http://mail.python.org/mailman/listinfo/python-list
