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.
