I don't care about knowing in advance; I mean more instrumenting the
ASDF process somehow to detect what *has* happened after the fact. I've
already done this in a hacky way by adding methods to internal functions
and (ab)using *macroexpand-hook*. I'm looking for nicer, possibly even
supported/encouraged ways.
