Shorthand ternary and switch assignments

Fairly sure this was proposed before. Can't remember where it wound up.

Edit:

Here are a couple:

[Proposal]: Escaping another (unused) scope pyramide with 'guard try catch'

Hello dear Swift community, this proposal might seem like some new syntax sugar, but it also aims to escape the 'do { }' scope from the 'do try catch‘ mechanism while making the existing error handling more powerful. Lets assume we have some sort of network type, which can throw a ton of different errors: struct TCPListener {        init(address: String) throws { /* implement */ }   func accept() throws -> TCPConn { /* implement */ }   /* ... */ } A way of implimentation might look like…

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! Soroush

I think one complication that needed straightening out was what happens when the throwing operation returns an optional?

Does the guard-let unwrap it? Do you then need to support guard-let-try-catch-else ??
