This works: 
    my $usefulans;
    foreach ( @$qablock ) {
        if ( $$_[ 0 ] eq $answer ) {
            $usefulans = [ @$_ ];
        }
    }
    print "\t\t----> @$usefulans\n";

...but it is terribly inelegant. I would like to replace it with a simple grep: 
    my $usefulans = grep { $$_[ 0 ] eq $answer } @$qablock;
    print "\t\t----> @$usefulans\n";

...but nothing (and I mean NOTHING...I've tried every permutation I could imagine, even throwing a map in for good measure) I do makes it work. No matter how I try to dereference the array of arrays, I end up with the reference address (e.g. "ARRAY(0x7fed6283b5d0)") instead of the legitimate list of data that I get from the foreach above. Am I stuck with the foreach, because this is something that grep just can't handle? Or is there something I'm doing wrong, which, done correctly, would make the grep work?

Thanks in advance,
