[swift-evolution] proposal for a even simpler guard.. => guard!

[Dominik Pich]

Hello,
often the guard statement is used to only unwrap optionals. multiple guards will cause a lot of ‘overhead’.
also often if it doesn’t work. there is no easy way we can gracefully recover ;)

so how about we do the same as with try/catch where you can use try! and have a guard!

the guard! could just throw an exception …

regards
Dominik
