but he wasn't asking for the name, he was asking for the
bound method object.

if all you need is the name, you can do:

    caller = sys._getframe(1).f_code.co_name

or perhaps

    def GET_CALLER():
        return sys._getframe(2).f_code.co_name

    ...

    caller = GET_CALLER()

(this gives the name used in the "def" statement that created
the code object, not the name used to access the function or
method.  they're usually the same, though...)
