If you need a infix operator that traps, here you have one ;)
infix operator ?! : NilCoalescingPrecedence
func ?! <T>(optional: T?, noreturn: @autoclosure () -> Never) -> T {
switch optional {
case .some(let value):
return value
case .none:
noreturn()
}
}
let x: Int? = nil
let y: Int = x ?! fatalError("Your message here")

I say it's a bit of an odd operator since it doesn't actually trap.
