Both of those are inferior to defining a new method with the right name and 
arguments and a docstring directing readers to the relevant function (which is 
what I would do for this situation at the moment).

The idea of the builtin would be to let introspection tools know that the 
documentation of the existing callable applies to the method as well, so that 
things like help(x.method) could retrieve something more useful than:

 >>> help(C().method)
Help on method method in module __main__:

method(*args, **kwds) method of __main__.C instance

Cheers,
Nick.
