I much prefer the foo:pre, foo:post way to this. Of course the first
time I saw this (apart from doing AspectJ work in Java) was in Lisp, and
what Matz proposed was lifted straight from Lisp. Using 'pre' and 'post'
as equivalents of 'def' seems a bit of a hack, to me. I think the
foo:pre syntax is more explicit in expressing what you are trying to do
that this.
