-T was made for people who make those mistakes.

Of course, with badly written programs you want to conceal everything, or as least as much as possible. You might even want to change some texts and some layout so people can't look up the source in Matt's archive.

$file = $q->param('file');
die "horribly" if $file !~ /^[a-z]+\z/;
open FILE, $file;

Or, untainting: 
$file = $q->param('file');
($file) = $file =~ /^([a-z]+)\z/;
open FILE, $file;
