I really think you may have a lot of trouble getting much of an overall
picture of something like MVP from any documentation.  Smalltalk tends to be
written using lots of short methods, anything with more that 5 lines of code
is considered "wordy" :-), so trying to follow what's happening on paper can
be very tortuous.  You've really, IMHO, got to sit down and experiment with
a live image, _that's_ when you see the power of the language.

I, and no doubt a lot of others here, could write a prototype demo of that
in Dolphin if you're interested.  It would be a bit simplified, data
persistence in a file rather than a database for instance, but would
probably give you a better idea of what's involved than reading through
documents.  Interested?, I've got a quarter of an hour to spare tomorrow :-)
I'll even add some comments to the code - a major concession for me these
days!
