[swift-evolution] [Review] SE-188 Make stdlib index types Hashable

[Howard Lovatt]

Proposal link:
https://github.com/apple/swift-evolution/blob/master/
proposals/0188-stdlib-index-types-hashable.md

• What is your evaluation of the proposal?

+1 but would like it to further and require all index types to be Hashable.

• Is the problem being addressed significant enough to warrant a change to
Swift?

It has been a problem for me in the past, however just requiring the
standard library ones to be hashable would solve the problem of third party
libraries, therefore suggest all hashable.

• Does this proposal fit well with the feel and direction of Swift?

Yes, this is the sort of thing that needs finalising before ABI stability
else we will be stuck with a problem.

• If you have used other languages or libraries with a similar feature, how
do you feel that this proposal compares to those?

Yes, Java, Scala, etc. Most languages have a hashable index so you can have
a set on indices etc.

• How much effort did you put into your review? A glance, a quick reading,
or an in-depth study?

Have read the review and have also implemented my own collections, which
used hashable indices.
