What you've given, and discussed, is an *implementation* of the
feature. If implemented, all that stuff will be hidden from the
user; she's left with the mere tasks of defining the pre- and
post-handlers. And that's what the RFC proposes, at the language
level. I don't see where you've offered an alternative to
defining the two separately.
