> - What is your evaluation of the proposal?
> Strong +1, especially for the unary operators. They make code clear,
concise, and elegant.
Pattern matching against one-sided ranges looks great, and being able to
use postfix “...” to create a sequence is niche but nifty.
> - Is the problem being addressed significant enough to warrant a
> change to Swift?
> Definitely. The excessive verbosity of “startIndex” and “endIndex” is a
drag on readability when subscripting.
> - Does this proposal fit well with the feel and direction of Swift?
> Replacing a long awkward incantation with a simple and aesthetic
alternative is about as Swifty as it gets!
> - If you have used other languages or libraries with a similar
> feature, how do you feel that this proposal compares to those?
> Closest would be Matlab with colons for ranges and the “end” keyword. This
proposal is far superior.
> - How much effort did you put into your review? A glance, a quick
> reading, or an in-depth study?
> Participated the discussion when it came up on-list, and read through the
proposal again now that it’s up for review.
