I am experimenting with this: If var! anOptional { anOptional // unwrapped, shadowing } if let! anOptional { ... // same } This compiler codebase is truly remarkable, so it should also works with If var! opt1 where opt1 < 27 { } or if var! opt1, opt2 { // both unwrapped } LM/On May 18, 2016, at 10:21 AM, Daniel Höpfl via swift-evolution <swift-evolution@swift.org> wrote: 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?
