With the previous PEP, people could create all sorts of subtle problems in their code (with or without transitivity!) and have no direct indicator of a problem. Clark and Ian made me realize this with their string/file/path discussions -- nobody is safe from implicit adaptation if adaptation actually creates new objects with independent state! An adapter's state needs to be kept with the original object, or not at all, and most of the time "not at all" is the correct answer.

+1, specially for the last sentence. An adapter with local state is not an adapter anymore! It's funny how difficult it's to get this... but it's obvious once stated.
