Hi,

I'm having trouble wrapping my mind around the ComputedAttribute class.  I
can't figure out a use case, mostly because I can't seem to understand what
it actually does.  Would someone be so kind as to provide me with a short
code example and explanation?

By the way, I'm loving Durus.  I'm a long time SQL user here, and I've taken
to object serialization surprisingly well.  I had my doubts, but they've all
been resolved.  Thanks for such a great project.
