in reply to Modules which improve system() ?

Ah! A Klingon programmer!

You would rather have your minions die then return in failure... Well, we can oblige...

You're looking for Perl6::Builtins, which you can use as follows:

use Perl6::Builtins qw( system ); system $cmd or croak "Couldn't run: $cmd ($OS_ERROR)";

Example was taken from TheDamian's Perl Best Practices.
