std.pattern..mixin temptes..std.concurrency

[BLS]

Hi,
Unfortunately Andrei has canceled his efforts on std.pattern.

Despite that I would like to hear your opinion regarding std.patterns in 
general,  I have a concrete problem in implementing patterns (like GOF 
stuff) with the help of mixin templates..

A concrete example (atm. an evolving idea) is the implementation of a 
mixin template based "observer pattern".      (publisher/subscriber)

I've startet a discussion on d.learn and
it would be very generous if you can have a look at :
news://news.digitalmars.com:119/i1094m$7b8$1@digitalmars.com
and follow the thread.

Further :
What do you think ?
  Would it makes sense to use the std.concurrency message passing system 
for OO patterns that require message passing ?
