Have you read the article? It describes a system which accomplishes much the same concept but more efficiently than with strings and with a bit more flexibility and feature support as well.

My bad, my comment was meant as a reply to the OP.

I think ApochPiQ knows your reply was really meant for the OP, though it was kind of a response to his reply, but what I think ApochPiQ is really trying to say is that his system is more efficient, flexible, and has more feature support. You're solution works, but... his is better, to be honest. I think that's the point he was making.
