Why dont support dispatch_once?

[huynhphan89]

Hi,

You said "I've found no need for dispatch_once in Swift" in #2 .
Could you please explain why no need to use dispatch_one in Swift?

Thanks.

Global variable (and constants) plus static members of classes/structs/enums with inital values basically initialised with the same dispatch once guarantees. And you can let the inital value be the result of a closure if you need any complex set up.
