Has anyone seen a longer article that compares several different MVC
and Model/Interface/Control design strategies, as used in, say an
Apple GUI, a Struts Web app and in Smalltalk MVC / Morphic / Tweak /
Seaside?   I would like to understand the Smalltalk heritage for
current UI implementation practices, and see code samples or
pseudocode for where they differ.

If so, I would love to read such an article.

I know the best way would be to build my own and judge how
maintainable they are, but I am not motivated to learn Java and
Objective-C :)
