[swift-evolution] [Pitch] Guard/Catch

I’d like to propose a guard/catch construct to the language. It would allow code to use throwing functions and handle errors fully, without straying from a happy path. do/catch can be a bit heavy-handed sometimes, and it would be nice to be able to handle throwing functions without committing to all the nesting and ceremony of do/catch.

Full proposal, which discusses all the corner cases and alternatives:

Looking forward to feedback!
