* What is your evaluation of the proposal?
+1. These are useful additions to the standard library.
Naming the first argument `initial` (in the `T->T?` variant) is consistent with
`reduce` and makes it clear (to me) that the initial value is part of the
result.
* Is the problem being addressed significant enough to warrant a change
to Swift?
Yes, these are good building blocks for other functionality and are useful
additions to the standard library
* Does this proposal fit well with the feel and direction of Swift?
Yes, in both naming and functionality it fits well with existing functions for
operating on sequences and collections. Using inout for the state argument
nicely leverages the fact that Swift can be functional without some of the
restrictions of a _purely_ functional language.
* If you have used other languages or libraries with a similar feature,
how do you feel that this proposal compares to those?
I’ve used iterate and unfold in Haskell. These additions are true to the
usefulness of those two functions, in a Swift style (see above).
* How much effort did you put into your review? A glance, a quick
reading, or an in-depth study?
Participated in the discussion and review of SE-0045 and the discussion that
followed it being accepted with modifications.
