[swift-evolution] Shorthand unwrap proposal

[Charlie Monroe]

There was a proposal not long ago floating around that there could be if and guard that would allow something like:

guard myReallyLongOptionalName! else {
	return
}

/// Now myReallyLongOptionalName is guaranteed to be nonnull

-- OR --

if myReallyLongOptionalName! {
	doSomethingWith(myReallyLongOptionalName)
}
