There is syntactic sugar for for-loops in Oz. You can easily iterate over
multiple lists like this:
for X in [1 2 3] Y in [a b c] do
{System.show X#Y}
end

There is "List.zip" which works like Haskell's zipWith.
It would not be difficult to write a function ForAllN which takes a list of N
lists and a n-ary procedure.
