This discussion is directed more towards monks like myself, who have been taught (directly or self-inflicted) the language through trial and error without ever having learned the fundamentals.
Throughout my existance here at PerlMonks, I have seen (and selflessly contributed to) numerous questions to which an enlightened monk simply answered see perldoc perlre, perldoc perlretut, perldoc perlvar, perldoc perlsyn, etc.
I have always struggled to figure out how one desides in which perldoc pages should they look for the answer. The answer that I have come up with, that I hope may be useful to others like myself, is simply www.perldoc.com. There one can bluntly write a question and get a list of perldoc pages which are relevant.
