Re: Inheritance that can add/remove and new occam?

[Nayef Baker <n.baker@xxxxxxxxxxxxxxxx>]

I am not sure wheather this is very good idea or not!

I used some quasi-dynamic approach to connect/disconnect process at run
time. Basically A calculated index of an array of channels allow various
processes to talk/end-talk on semi dynamic way..

It would be great if Occam allows fully dynamic channel creation/ 
destruction..
