[swift-evolution] [Review] SE-0047 Defaulting non-Void functions so they warn on unused results

[Howard Lovatt]

> 	• What is your evaluation of the proposal?

Great idea

> 	• Is the problem being addressed significant enough to warrant a change to Swift?

Yes I think so, currently the declaration line is very cluttered with lots of noise up front that hides what the line actually does. This proposal removes some of that noise.

> 	• Does this proposal fit well with the feel and direction of Swift?

Yes, Swift is clutter free and tries to pick as the default the most common case

> 	• If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?

I have used languages with the current Swift behaviour of having to explicitly initiate the warning and they like Swift tended to be a pain. Either the declaration got cluttered or the annotation was omitted.

I have used products like lint for C and appreciated that it automatically warned about unused returned values.
