This is the correct solution IMO. The principle of least surprise should  
dictate that a.foo should always mean the same thing. All that is required  
to enforce this is to make the "hook" function have a different name.

I think the two mechanisms of overriding default behavior:

1. Use a hook, to define the basic minimum functionality.
2. Implement the same-named method, but you must implement ALL  
functionality (possibly deferring to the global function if necessary).
