[swift-evolution] [Idea] if let value!

[Daniel Höpfl]

Just an idea: Why don’t we think about it similar to try?

var anOptional : String?

let? anOptional { /* use it, but cannot change it */ }
let! anOptional { /* use it, without checking, cannot change it */ }

var? anOptional { /* use it, can also change it, */ }
var! anOptional { /* use it, without checking, can also change it */ }

Is it allowed to set it to nil in the var case? Hard to say.
