Simple... and neat using File::Temp:

use File::Temp;

sub cmdrun {
    my $cmd = shift;
    my $out = File::Temp->new();
    my $err = File::Temp->new();
    local $/;

    `$cmd >$out 2>$err`;
    $?>>8, scalar <$out>, scalar <$err>
}

use Data::Dumper;
print Dumper cmdrun( q(perl -le "warn q(NOISE); print q(OUTPUT); exit 
+42;") );
