Matching optionals in a switch statement

@Martin

Question 1: case 1? is never executed. Should the compiler detect that and emit a warning?

That's a good idea.

@Martin

Question 2: Is that fundamentally different from the integer case, or should it compile as well?

It ought to comple as well. That's a bug.

Thanks for raising these issues! If you have a moment, both of them are worth filing on bugs.swift.org, if you haven't already.
