RemoveSet( set, elm )
RemoveSet
removes the element elm, which may be an object of
arbitrary type, from the set set, which must be a set, otherwise an
error will be signalled. If elm is not an element of set nothing
happens. If elm is an element it is removed and all the following
elements in the list are moved one position forward.
