True, relying on perl's special variables can be confusing, although
I do like $_, especially in short loops that just iterate over arrays.
foreach (@list) {
print "$_\n";
}

lazy people anyway? I mean, lazy as in work smart, not hard.

Cool! That beats the hell out of trying out stuff in long "perl -e ''"
