Proof step 5 from proof newref-1dim (previous step)

r0 ∈ st, r0 -- sk ∈ st, ∀ rk. rk ∈ addarray(r, ty, i, st) → rk .ref ≠ r0 ⊦ r = r0, r0 = jvmref

Heuristic quantifier closing applied rule all left

And obtained the following new goals

Proof step 4:
⊦ r ≠ r0 → (r -- sk ∈ addarray(r0, ty, i, st) ↔ r -- sk ∈ st)

Rule argument
