The Grand Central stuff is using the new block syntax introduced for Obj-C 2.0. That has been discussed publicly so it is no longer embargoed under NDA. Any ruby implementation would likely build on the obj-c block syntax, so that is safe to discuss. How it would specifically tie in to the Grand Central API is off limits until September. cr On Jun 9, 2009, at 11:08 AM, Matt Aimonetti wrote:
Rich,
I believe (but I'm not sure) that Grand Central Dispatch as well as a Snow Leopard are technologies under NDA and can't be discussed publicly on the mailing list. I'm not in the know and can only speculate. My guess is that MacRuby will eventually take advantage of GCD but I'm afraid, we will have to wait for Sept. to know more about that.

It's also pretty clear that any first-class development language on Mac OS X, going forward, will have to support this. Ruby has all sorts of block-based goodness already and Laurent is busily implementing JIT for MacRuby, so I speculate that GCD may well be in MacRuby's future.
Has anyone looked into this possibility, if only to the extent of sketching out what language extensions might be needed?
