Feature: jump to next/previous case

[ncik-roberts]

(This is an idea for a feature.)

If you're editing a large match expression, it could be nice to jump to the previous/next case, e.g.:

let f x =
  match x with
  | A ->
    let x1 = ... in
    let x2 = ... in
    ^
    (* many dozens of lines of code *)
  | B -> 3

If my cursor is as indicated in the A case, it would be nice to jump to the B case.

A sensible place to put this feature might be in the jump rpc. Right now, that supports jumping to the top of a let, match, or function; it might be easy to extend it to support next-case and prev-case.

(I started to look at this but it wasn't trivial so I thought I'd log this issue.)

Just out of curiosity, will this be cyclic, such that if the cursor is at the last case, does the next function cycle back to the first case or just displays a message indicating it's at the last case?
