I uploaded a new version of multivalues.zip that includes a
test() function.  I thought "test" sounded better than "compare"
for general predicate tests:

   if (test(all_of(a), pred(), any_of(b)))...

vs.

   if (compare(all_of(a), pred(), any_of(b)))...

Let me know which you prefer or if you have a better idea.

The ^ operator is still supported until there is some consensus
on another operator or on supporting no operator.  Another option
is to provide support for several operators so one can choose
whichever one likes best.
