[swift-evolution] [Proposal Draft] Literal Syntax Protocols

I wouldn’t use the Type suffix, because I believe this will create even more confusion with the associatedtype IntegerLiteralType from the current IntegerLiteralConvertible itself.

I rather like this one.  It produces: `Syntax.Literal.IntegerProtocol`, which is honestly
the best I've seen so far *and* it might get past the Dave test.

I’m curious to see what Dave thinks of this as well.  

`Syntax.IntegerLiteralType` is another that popped into my mind this morning.  I don’t recall if that has been mentioned yet.  The idea here is that an integer literal *can be typed as* a type that conforms to this protocol (the type suffix *is not* used in the sense that it used to be used in things like `SequenceType` which had the semantic that conforming types *are* sequences).  


Thank you for bringing this into the conversation!

How about:

public enum Syntax {
    public enum Literal {

        public typealias NilProtocol = ...
        public typealias BooleanProtocol = ...
        public typealias IntegerProtocol = ...
        public typealias FloatProtocol = ...
        public typealias UnicodeScalarProtocol = ...
        public typealias ExtendedGraphemeClusterProtocol = ...
        public typealias StringProtocol = ...
        public typealias StringInterpolationProtocol = ...
        public typealias ArrayProtocol = ...
        public typealias DictionaryProtocol = ...

extension Array : Syntax.Literal.ArrayProtocol { ... }
