It's a powerful analogy, for sure!  Right inline with the Smalltalk way of
thinking about programming, something I truly appreciate.  Come to think of
it, the combination of Vista Smalltalk/DLR[1] + IronPython + Kamaelia +
Silverlight (once Silverlight gains support for sockets) == my mouth
drooling with the combination of possibilities. :D

Am playing with this now.  In the mean time, one problem I ran into that
requires the yet to be implemented nested yield statements in IP 2.0,

IronPython 1.1 (1.1) on .NET 2.0.50727.42

Beyond the above issue, things seem to be playing nicely which is really
great!  I'll run through the provided sample now and let you know if I run
into any issues.

Thanks, Michael!
