Ah, that's what I thought all along but it sounded cool when Mr Adams said it wasn't evaluated anymore but reduced (?) ... >> What kind of things or problems could or should you solve >> with macros? > > Whenever you find yourself forced to use `eval` ? 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. -- underground experts united https://dataswamp.org/~incal
