[Pitch] Rename `index(of:)` and `index(where:)` to `firstIndex(of:)` and `firstIndex(where:)` respectively

timv · 2016-07-24T09:58:42.000Z

`firstIndex` is completely unambiguous, whereas with `index` people might wonder which index is returned. Also, if `lastIndex` methods ever get added to the standard library, they will be a lot more consistent with `firstIndex` than with `index`.

On the other hand, `index` is short and simple, and people might not care whether it is the first index that matches or a different one. Still I think `firstIndex` is more in line with the naming guidelines.

Thoughts?

Is your proposal going to make the swift3 window?

It should. I'm planning on merging it and launching the review
if Chris L doesn't beat me to it (which I hope he will ;-)).

I’m still waiting to be told that it is ready. You guys appear to still be iterating in the PR.

The latest comment from Brent on the PR indicated that it's ready, I
believe.
