[swift-evolution] ternary operator ?: suggestion

It's a nice, consistent proposal, but I don't feel like this solves any of the complaints about the existing ternary operator:

- It's not obvious what it does when you first learn it.
- The '?' doesn't have anything to do with Optionals.

It is a way to put 'switch' into an expression. I'm not a fan of the two different colons, but that's "just" syntax.
