Is it really in a month? Who said that? Chris told everyone that until August 
we can still talk about changes for Swift 3. The evolution repository says 
Swift 3 will drop late this year not mid. But it’s the core team to decide 
which proposals they would prefer. This one would be way easier to complete 
until Swift 3, but it also implies that my and your proposal should be 
accepted/deffered for Swift 3.x. Otherwise this would be strange just to rename 
protocol<> to Any<> and not to accept the enhancement of it. :D

I've come to the conclusion that the best course of action is to propose this 
syntax-only change for Swift 3, and then advance the generalized existential 
proposal after Swift 3 ships. You can ask the reviewers to consider your 
proposal instead of this one, but given that the Swift 3 release date is in a 
month I don't think it's likely that anything more substantial than this will 
be accepted. You are welcome to try, of course.

Austin do we really need this 3rd proposal? This makes my original one really a 
waste of time. I was trying to solve https://openradar.appspot.com/20990743 
with the original `Any<>` proposal when Swift 3 ships. Your other proposal 
would enhance it without introducing breaking changes.

To that end, I’d suggest Any<>,Any<Any, XX>, and Any<Any<XX>> all cause 
warnings.
Why would these cause warnings?

func foo(any: protocol<>)

func foo(any: protocol<Any>)

func foo(any: protocol<Any, ProtocolA>)

func foo(any: protocol<ProtocolA>)

Everything is already fine today.



I agree, adding new warnings is out of the scope of this proposal.

My feedback is that we should narrow what is acceptable for Any as much as 
possible, because relaxing restrictions in the future won’t break existing code.

To that end, I’d suggest Any<>,Any<Any, XX>, and Any<Any<XX>> all cause 
warnings.
