Ah, that's what I thought all along but it sounded cool when
Mr Adams said it wasn't evaluated anymore but reduced (?) ...

OK so the hierarchy is:
1. `defun' (best)
2. `defmacro' (at least better than `eval')
3. eval (worse)
That what you meant?
Can one summarize in human language without references to Lisp
perhaps when macros are used? I used them so seldom I don't
know why people use them, even. I guess I did so good now I'm
ignorant instead.
