An excellent point, although the syntax gets a bit tricky, especially for someone just getting started. Using a custom property set as an array only incurs about a 50% performance hit, as well -- easily fast enough for this purpose. I edited the wiki page on properties to add some sample code to show how to do this. It's at:
