Registry of Methods via Decorators

I think you're going to need a metaclass for this, e.g.::

 >>> import inspect
 >>> def registered(func):
...     func.registered = True
...     return func
...
 >>> class RegisterFuncs(type):
...     def __init__(cls, name, bases, classdict):
...         cls.methods = []
...         for name, value in classdict.iteritems():
...             if inspect.isfunction(value):
...                 if hasattr(value, 'registered'):
...                     cls.methods.append(name)
...
 >>> class C(object):
...     __metaclass__ = RegisterFuncs
...     @registered
...     def first_func(self):
...         pass
...     @registered
...     def second_func(self):
...         pass
...
 >>> C.methods
['first_func', 'second_func']

If you just want to store *all* method names, you can dispense with the 
@registered decorator and the hasattr() check.
