> The revised version of the proposal can be found here:
> • What is your evaluation of the proposal?
Overall +1. Two reservations:
1. Functions like `signum()` that return a property would read better as
2. I have found `BitwiseOperations` useful as an extension to both Bool
and Set and for a custom set type. Therefore would prefer its retention and
even more preferably that Bool and Set implement it.
• Is the problem being addressed significant enough to warrant a change to
Yes, generic representation of integers is useful.
> • Does this proposal fit well with the feel and direction of Swift?
Yes, particularly the re-arrangment of the protocol hierarchy is in keeping
with the rest of the restructuring of the standard library.
> • If you have used other languages or libraries with a similar feature,
> how do you feel that this proposal compares to those?
Yes, many languages I use allow generic numeric functions to be written and
I write my own numeric functions and will therefore use these protocols.
> • How much effort did you put into your review? A glance, a quick reading,
> or an in-depth study?
Quick read, but have pulled my hair out trying to write generic stuff in
Swift as it stands now.
