There was a problem hiding this comment.
This is now failing perltidy tests here, there is a misplaced space: push(@return, $x) if (grep { $_ == $x } (@_)) > 1;.

This will be merged immediately. We rushed the merge of openwebwork#1000 before the workflow completed I think. Thus we didn't see this at that time.

Sometimes I want to check if there are repeats in some list. This macro will make that easy to code in a PG problem.
Use
!repeated(@array)to test (boolean true or false) if@arrayhas repeats. If it does and you actually want to see them,repeated(@array)will be the list of repeats. Subject to the special consideration noted in the POD.
