I just found this in the archive:

That example Nathan provides of mixin is a lot cleaner than a different
example (from a different poster on a different site) i was looking at.
 I could probably use the method Nathan proposed in a pretty clean way.

i'm justified for using this multiple inheritance workaround to keep the
core framework untouched?

Does anyone else have a different approach or suggestion?
