in reply to Rules-based Perl?

You may want to look at Language::Prolog on CPAN. Prolog is another of the rules based languages. I have never used this module so I am not sure how well it is integrated with Perl. Prolog itself is pretty good if you can twist your head around the rules-based stuff (which it looks like you already know).

    I've been learning to use Prolog in the last 2 weeks and yes, it's quite different to use rules based languages. You are right, you have to be able to twist your head around to understand rules-based stuff! Great food program btw, i'll use it next time i try some chicken recipes :)

[hippo]: Can anybody suggest a scalar value of $x for which ($x && !length $x) is true?
[Corion]: hippo: If you have a Unicode-wise Perl then likely some zero-width characters in $x would work. Maybe $x = "\x{200b}" works.
