Evan,

Thanks for the research!

It's not bad, if anyone wants to get a copy let me know. A lot of it
applies to GUI stuff which isn't our primary focus, but no worries.

One really good take-away is that inheritance is very often the wrong
model; OO supports it but only use it when it makes sense. A lot of the
book is about providing other ways to connect objects of different
classes (often with aggregation, or specialized forms of aggregation,
rather than inheritance).

Interesting.

Not surprisingly, we have discussed concepts here already. For example
"lazy initialization":

http://en.wikipedia.org/wiki/Lazy_initialization

We are considering this in the DNS Message API, because you don't need
to do all of the expensive parsing in many cases.

Anyway, I propose we look at the Wikipedia page when we are designing
and see if we are re-inventing the patterns there, or if they can solve
our problems. :)
