It does not seem out of place that a quest for canonical form should drive monks. I tend to agree that all ways to express a solution are not equal. Perl is beautiful in its expressiveness, but it does not follow that a solution has value merely because it is excessively clever. Sometimes, other principles should guide. If you need a efficient solution, Perl can provide...but lo' you can get a playful take as well. The context of a problem should guide the monk's post as context guides Perl itself.
