I'm just going to comment on this one stylistic point -- only use a
macro when you need to control the evaluation of arguments, never in a
case like this where an ordinary function would do. The reason is you
can't use a macro in REDUCE, APPLY, or any other context where you need
to treat it as a first-class value.
