Poisoned null attacks against Perl scripts still work in the current Perl interpreter, several years after the technique was discovered.

I find this surprising. IMO the Perl interpreter should barf if asked to pass a string that contains a null to a system call that expects a null-terminated string. At least doing this for open() seems like a no-brainer.

I know the Perl core developers are a smart bunch, so maybe there's a downside to doing this that I'm missing. Can anyone shed some light ?
