Well, I would make coding standards for good programmers,
and from a good programmer, I would assume he/she knows
the language. Non-perl programmers shouldn't program Perl.
And as a manager, or tech-lead, I wouldn't allow non-Perl
programmers to touch Perl code.
Perhaps rule 0 should be: "People who can't program in Perl
are not allowed to touch the code".
$_ is one of the most basic things in Perl. If
you have problems with the readability of $_,
you shouldn't call yourself a Perl programmer.
