Well, I'm no perl guru, but I know it IS possible to obfuscate the code enough that no one in their right mind could read it... for example:
Code:
#!/usr/bin/perl
@a=(Lbzjoftt,Inqbujfodf,
Hvcsjt); $b="Lbssz Wbmm"
;$b =~ y/b-z/a-z/ ; $c =
" Tif ". @a ." hsfbu wj"
."suvft pg b qsphsbnnfs"
. ":\n";$c =~y/b-y/a-z/;
print"\n\n$c ";for($i=0;
$i<@a; $i++) { $a[$i] =~
y/b-y/a-z/;if($a[$i]eq$a
[-1]){print"and $a[$i]."
;}else{ print"$a[$i], ";
}}print"\n\t\t--$b\n\n";

Try running that... Then try to figure it out...

NAME

       Perl::Critic::Policy::Variables::ProtectPrivateVars - Prevent access to private vars in other packages.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       By convention Perl authors (like authors in many other languages) indicate private methods and variables by inserting a leading underscore
       before the identifier.  This policy catches attempts to access private variables from outside the package itself.

CONFIGURATION

       This Policy is not configurable except for the standard options.

HISTORY

       This policy is inspired by a similar test in B::Lint
