FWIW: there is the Safe module to disallow certain Op-codes inside a (r)eval.

use Safe;

$compartment = new Safe; 

$compartment->permit(qw(time sort :browse));

$result = $compartment->reval($unsafe_code);

Unfortunately I couldn't find a way to disable compiletime blocks like BEGIN and there doesn't seem to be another way to disable or override BEGIN...

I'd love to be corrected.

UPDATE

oh Keyword::Simple could do the trick :)
