While this may be a good idea, John_M._Dlugosz, it may get tiresome to each particular anonymous monk that posts each and every time they post.
in reply to use strict and warnings for newbes
I am not trying to sound rude, but what if that person (he or she,) is actually very skilled in the language, and already know to use strict, and -w in their snippets or code? It might just make them consider perlmonks.org just a place where they think new people don't know anything about the language.
I think it's just fine to leave it the way it is, since newbies generally learn quite quickly that they should use strict, and -w... at least I did, and I know of many others :-).
That's just my quarter for this subject ;-).
