Most of the examples are out in a separate file. I'm not sure which of
them, if any, should be blessed with a mention in the PEP itself.

Part of the mess with that one is that it really needs an author's
eye; I can show that this could be done cleanly with the new syntax,
but I can't make it both clean *and* trivially provably performing the
same job. It'd probably want some other way of rendering the exception
to text.
