If you're seriously telling me you instantly spot the bug (if that were real perl, i don't know perl) without having seen the talk before, then congratulations,

If you're seriously telling me you instantly spot the bug (if that were real perl, i don't know perl) without having seen the talk before, then congratulations, nobody else did, please start auditing perl software. I've fixed that bug in code as far back as 2000. There've been discussions on that anti-pattern on PerlMonks for at least a decade.
