Also "As const view" could move up next to "As rvalue view".

@jensmaurer Do you think those are useful rearrangements?

And we can move "slide view" up to just after the "adjacent" views, since they both produce "subranges" rather than elements, i.e. elements of the original range are seen repeatedly.

There's room for further more improvement. Here's my compiled suggestion.

  • Transforms: (All, as rvalue, as const, transform, common, elements)
    • (All, common) change the input range's interface only.
    • (As rvalue, as const, transform, elements) transform the elements.
  • Subsets: (Filter, take, drop, counted, stride)
  • Subranges: (Split, adjacent, chunk, slide)
  • Packers: (Zip, cartesian product, enumerate)
  • Join, reverse.

Generally agreed here; maybe "transforms" -> "transformations".
