The PEP lists five built-in decorators, all of which support this behavior:: @overload, @when, @before, @after, @around

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.
