(* This should be able to be improved, to require less proof steps: just put only the nonLaterable things in the argument P.
However, my initial attempts failed. This is because the order matters in which things are put into the goal,
< order matters because we don't make progress on (∀ a, H) ⊢ (∀ a, H) ∗ R >
and the current approach keeps the order currently found in the environment, which seems to be okay.
Maybe we need a MakeSep which determines heuristically which goals should be put on the RHS? *)
