Sorry! do not attribute to jest what can be explained with
simple stupidity - or so the saying goes ... :-)

Perhaps it was the mentioning of WHEN and UNLESS (that
remove the need for PROGN and the "else" in LISP), perhaps
it was seeing the use of a list comprehension without a list
producing one that was not wanted, perhaps I was
simply trying not to like the "andalso" (which is only
possible since R13A
http://erlang.org/doc/reference_manual/expressions.html#short-circuit-expressions)
or perhaps there is a reason for my "if" being nonsense and
that reason is not to be circumvented with "andalso" ...

... but I seem to be too stupid to see that (yet) :-)
