Not so. Take let as the favorite example of a special form that is very necessary in any functional paradigm. What may be true for if is not true for forms that in addition to require special evaluation rules of subforms, imposes _structure_ on its subforms that "violate" the normal evaluation rules. In fact, if is a very special case special operator. It is better to begin with something like let and then deduce if, than to begin with if and try to get anywhere at all. #:Erik -- Travel is a meat thing.
