Thanks everybody for a great response it seems I still have a lot to do.

I'll definitly be adding Code Templates looking at perltidy and refining the list with your comments. Adding some justification for each statement will also be a worthwhile exercise. So sometime soon you may expect the final perlmonk audited list:)

I think Wally hit it on the head by pointing out what I should have said at the start that this is intended as a list for Novices or bad programmers, new people who join our team and usually have no knowledge of Perl. Perl Gurus are a verifiable rarity and we have so far only managed to hire a couple of people with any real Perl knowledge. A Language migration course is what we really need to help quickly convert them from their native language

I'm thinking many ways means many guidelines
