using std.concurrency for std.pattern message passing

[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 (not only the 
GOF stuff) with the help of mixin templates..

A concrete example (an evolving idea) is the implementation of a mixin 
template based  observer pattern (publisher/subscriber), discussed on 
d.learn.
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 :
Would it makes sense to use the std.concurrency message passing system 
for OO patterns that require message passing ?
