greetings: not sure if y'all like to use eval for regexp speedup, eg: 
$fast = sub {
    my $match = qq@ return 1 if m!foo!o; @;
    my $code = eval "sub {$match ; return 0}";
    return $code;
};

..and then using it later on: 
    while(<>) {
        next unless &{$fast};
    }

this is a charming trick when it works, but i've only done it with the eval'd sub returning 0 or 1. Has anybody tried this with other return values? Ideally, i'd like it to read: 
    $match = qq@  return (\$1,\$2) if m!(foo)(bar)!; @;

...however, it seems like this is not really working :( attempts to capture the return have set the return value to 'CODE'. what's up with that? any thoughts/hints/experience?

dorking hard,
gleeco
