@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?
Brandon
Without the '@', you're declaring a parameter labeled 'autoclosure'.

What about “inout” then?
And duh! I completely forgot about parameter labels -_-

'inout' is a special case, and we've reserved it as a keyword. There's a thread about moving 'inout' to eliminate this special case.

Ok thanks I’ll look into it! It may remove some confusion / unclarity for me

Hi,
I still would like to better understand that.
Is the reason to use `@` to hint the compiler / optimizer? Why not make `autoclosure`, `noescape`, etc. special keywords as well?
