I don't feel like I've learned much about Go from this article.

    make(chan bool, 1)

what is that 1 for? Why is it not using constructor sytnax shown earlier? (`Chan{bool}` or `BoolChan{1}`?)

`go function` is nice, but in ObjC there's `dispatch_async()` and `NSOperationQueue`. Go does some magic with green threads, segmented stacks and whatnot, but the article doesn't elaborate.

And for an Objective-C developer Go's lack of proper interoperability with Cocoa is disappointing:

BTW:

   (CGRect){0, 0, 320, 480}

is valid in ObjC (doesn't apply to classes though).
