> • What is your evaluation of the proposal?
+1 This is a small, but very useful addition. I like the argument label `into`, and using it to distinguish between the two implementations.
> • Is the problem being addressed significant enough to warrant a change to Swift?
Yes. Reducing and accumulating into structures like arrays or dictionaries can be very powerful.
> • Does this proposal fit well with the feel and direction of Swift?
Yes. It makes it easier for developers to write higher level code with good, predictable performance.
> • 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 recall other languages that provide different implementations of higher order functions with different performance characteristics. However, I've used other languages that provide different data structure implementations with different performance characteristics.
> • How much effort did you put into your review? A glance, a quick reading, or an in-depth study?
A quick reading of the proposal and the other reviews so far.
