A while ago, David Lorenz and I discussed being able to advise a
lambda application expression before the arguments were evaluated.
Then you could turn any procedure into a macro (depending on what

I'm not sure what "weaker than" means.  I think one advantage of
aspects over macros is obliviousness, but that's still somewhat
controversial.
