This is true whatever you are decorating - class method, static method, instance method, function. And FWIW, the term "class method" has a definite meaning in Python. > Using a class method to decorate another class method is > going to be tricky.

The problem is then that this function cannot easily access the class object - which is what the OP want. > > You're going to have to show us the actual code you are > having trouble with, or else (probably more useful, really) > try to put together a minimal example of what you are > trying to do and show us that code. +1 on this -- http://mail.python.org/mailman/listinfo/python-list
