[swift-evolution] What are the rules for including @ with attributes/keywords and the possibility of removing it

[Brandon Knope]

@noescape
@autoclosure

Is there a particular reason why there is a @ prepending these attributes/keywords?


func test(@autoclosure test: () -> Bool) -> Void

vs.

func test(autoclosure test: () -> Bool) -> Void 

It seems cleaner/clearer without @ sprinkled everywhere, but what is the rationale behind needing the @ symbol?
