Regarding the PASCAL evaluation with "guards" on the IF clauses.
Standard PASCAL (If there is such a beast) does not guarantee order of
evalutaion.  Any code which relies upon order of evaluation to work is
certainly non-portable.  DOMAIN Pascal does provide a solution:  Use the
IF x and then Y then construct.  This aloso, of course, is non-portable.

If you want portable, robust code the only option is to use the nested
iff type of thing.  Messy, but guaranteed.
