Message-Passing

[Nathan M. Swan]

I want to applaud Sean Kelly and everyone who worked on std.concurrency 
for a great API, and wish that I could easily write Cocoa applications 
with it.

I'm writing a screen recording program in Objective-C, and to make sure 
each frame has an equal length, I have two threads: one that takes the 
screenshot at certain intervals, the other that assembles it into a 
quicktime movie. After writing an implementation of a thread-safe queue, 
where the picture-taking thread adds and the assembling thread removes, 
I realized the huge similarity between what I'd done and std.concurrency.

The std.concurrency module would have made hours of effort in ObjC take 
five minutes in D. Well done!
