> The review of “Defaulting non-Void functions so they warn on unused results” begins now and runs through March 21, 2016. The proposal is available here:
> • What is your evaluation of the proposal?
Strongly in favor of this. I’ve added the existing @warn_unused_result all over the place in my own code and it helps keep me honest - but I’m kind of tired of the boilerplate!
> • Is the problem being addressed significant enough to warrant a change to Swift?
Calling it a “problem” is probably not the right term in this case, but yes, I think change is warranted due to Swift’s willingness to help developers avoid bugs by omission.
> • Does this proposal fit well with the feel and direction of Swift?
Yes, I believe so. Swift already alerts you when you don’t mutate a var or cover all possible switch cases and this feels like a very similar situation.
> • If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?
I don’t think I’ve used any with this sort of default.
> • How much effort did you put into your review? A glance, a quick reading, or an in-depth study?
Followed the mailing list discussion, read the proposal, encountered the issue in my own code.
