I went away and now I'm back ...

I read up on predicate, clearer and trigger attribute options and have revised the code. Though it bombs with the following error:

Can't call method "Dbase" on an undefined value at pizzle.pm line 29.
Compilation failed in require at test_pizzle.pl line 4.

Let me know if you have any further comments, before I begin to start to hit head here
