in reply to Checking to see if Taint mode is enabled

${^TAINT}

Reflects if taint mode is on or off. 1 for on (the program was run with -T), 0 for off, -1 when only taint warnings are enabled (i.e. with -t or -TU).

In Perl 5.8.

You have to use that new global inside an eval for backwards compatibility:

sub is_tainted {
   my $taint;
   if ( $] >= 5.008 ) {
      $taint = eval '${^TAINT}';
   }
   else {
      # some work around ...
   }
   $taint;
}
