>>> def add_initial_argument(func):
... def f(*args, **kwargs):
... return func('newarg', *args, **kwargs)
... return f
...
>>> class C(object):
... @add_initial_argument
... def foo(newarg, self):
... print newarg
...
>>> C().foo()
newarg
>>> C.foo(C())
newarg
I don't see an error thrown with either the bound or unbound methods...
