You can taint a reference without manually flipping the taint flag, although it doesn't come directly from the outside: my $str = shift; # $str tainted my $reg = qr/$str/; # The $reg blessed magic object is tainted system echo => $reg; # err: $reg is tainted on interpolation I test for this amongst other things in Taint::Util's t/usage.t test. It also allows you to taint any reference (including coderefs) but that's manual mucking around with SV*'s as has been pointed out.Thread Previous | Thread Next
