The i-layer was the best solution for the problem, given VFP's
object model. Python has a very different model, and the i-layer
pattern is not the best solution by a long shot.
Take a look at the ClassDesigner code; specifically, the
ClassDesignerControlMixin.py file and the ClassDesignerFormMixin.py
files. This is more the pattern that should be used for developer-
level modifications to the framework. Write a mixin that supplies the
needed mods, and instead of creating hard-coded subclasses, generate
the classes on the fly.
I'm sure that if I grokked metaclasses better, I would probably want
to go that route instead, based on what I know about them. But that's
beyond my skills at the moment.
