[Review] SE-0065 A New Model for Collections and Indices

Huh, that clarifies something. How about the non-`ing` variants?

  collection.travel(5, from: i)
  collection.stride(5, from: i)
  collection.advance(i, by: 5)

Active verb phrases are reserved for methods with side-effects according
to the API guidelines.

Is there *any* way of using a verb to indicate an argument is being modified? If not, I think that's a serious omission in the API guidelines.
