Thanks for the advice Gabriel. The use case I have is that I'd like to
be able to decorate classes and even modules in this way:

>>> import announce
>>> import spam
>>> announce.announce_module(spam)

Here, "announce.announce_module" has a look in "spam", finds all the
functions and instancemethods, and decorates them (rebinds them) by
announcing calls to these functions and instancemethods.

It's something I've found useful, though clearly the behaviour of
"spam" has been drastically changed. I'd appreciate advice on better
ways to achieve this kind of thing, or why it doesn't look good.
