Actually @before and @after don't support __proceeds__,
according to the first draft anyway.

I think I would prefer to *always* pass the next method
to @around methods, which always need it, and *never*
pass it to any of the others.  What use case am I missing?
The one in the PEP involves foo(bar, baz), not a very
convincing example.
