  I have just tried to make Allegro CL report information on a macro-to-be-
  compiled such that it would advise the functions that had used a compiled
  version of same to recompile themselves the next time they were called,
  advise that would obviously be overridden if the function was compiled
  along with the new macro.  The experiment failed spectacularly (the lisp
  image died!) and will result in a bug report if I can convince myself that
  it was not a dumb thing to do.  But I somehow think it should have worked.

Act from reason, and failure makes you rethink and study harder.
Act from faith, and failure makes you blame someone and push harder.
