In practice, @around is mostly used for application-defined special cases, and there is no higher authority than the application who needs to override things. If a library needs special combinators internally, it's better off making them lower-than- at around precedence. Normal, before, and after methods are usually adequate for libraries. (Aside from special-purpose combinators like the @discount example.) (1) Would it be reaonable to say this in the PEP? (2) Would it be reasonable to leave out (or at least, leave for another PEP) the extension methods like discount?

There ought to be a way to preserve with each PEP a separate document containing a more lengthy discussion of the rationales and consequences. Similar to the way that the Federalist Papers is often used to interpret the meaning of the U.S. Constitution.
