If this particular product was a python based one, I could easily add a def __getitem__(self, key) method to my class so that one would be able to go:

<dtml-var "MyProductClassInstance['somekey']">

In a ZClass I can't add a Python Script called __getitem__ because of the underscores. Any solutions to this? Derive your ZClass from a Python base class that redirects "__getitem__" to something you can define in your ZClass.
