DIFFERENCE is retained as a synonym for EXCLUDE.
Why do you say it won't work? It appears to be correctly returning only the
different characters as would be expected when dealing with a string. What
it returns depends on what the series is made up of.
difference "ABCDEFG" "ABCDEFGH"
==H
difference [1 2 3 4] [1 2 3 4 5 8]
== [5 8]
difference ["the" "cat" "sat"] ["the" "cat" "sat" "on" "the" "mat"]
== ["on" "mat"]
