AddSet( set, elm )
AddSet
adds elm, which may be an elment of an arbitrary type, to the
set set, which must be a proper set, otherwise an error will be
signalled. If elm is already an element of the set set, the set is
not changed. Otherwise elm is inserted at the correct position such
that set is again a set afterwards.
