Good point. My distinction was based on the perception
that monad /: and /:~ must do the work of actual sorting,
whereas dyadic /: with y in i.#x is merely selection in
already given grading (with possible duplicates in y,
which preserves original order).
Maybe a better approach in merge is to try to find a permutation
rather than grading.
