Don't be that sure, my friend. I found one, say, Clark Kent, that put in "Clark" as a password. When I complained and ordered him to change it to a real password, he say "but how will I remember my password if it is more difficult than that?".
There is no lower limit to intelligence, it seems :-)
The very nature of Perl to be like natural language--inconsistant and full of dwim and special cases--makes it impossible to know it all without simply memorizing the documentation (which is not complete or totally correct anyway).
