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

[David Sweeris]

If we go with the “Compiler” alternative, it might make sense to put things like the language/toolchain version, host, target, etc there:
if Compiler.language.version >= 3 { celebrate() }
if Compiler.target.cpuCount * Compiler.target.coreCount > someValue {/* parallelize something differently than you would have otherwise */}

Or maybe someday we could use it for expanding the language’s syntax:
// Not sure if “Compiler.appendSyntax(...)” would be better
Syntax.append(/* something which makes sense goes here */)

There was something I was going to reply to yesterday which included a suggestion to add something to the Syntax namespace, but I can’t find it now, so I guess that draft got scrapped or something.

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).

However, I don’t plan to incorporate every alternative from the bikeshed into the alternatives section unless folks feel it is critical to do so. I would prefer that everyone save their personal favorite(s) for the review period and continue the bike shedding at that time.
