Yes, that's right. The code to fix it would make it too long :(

There are even two kinds of "standard" module - those that come with a 
Perl distro, and those you can get from CPAN. So we'd have to define 
exactly what is allowed and what isn't. I'd say modules should be 
disallowed, as the purpose of the one liner game is to show what can be 
done with the language itself.

Clever and devious use of modules would be another type of competition, 
I think. I don't know what the rules and goals of this game would be, 
I'd have to think about it.

Neither had I, but I had faith that there would be one. A quick search 
on http://search.cpan.org, and there it was! That happens a lot with 
Perl - the solution is often just on CPAN!
