Proof step 6 from proof newref-1dim (previous step)

r -- _type ∈ addarray(r, ty, i, st) → (r -- _type) .ref ≠ r0, ∀ rk. rk ∈ addarray(r, ty, i, st) → rk .ref ≠ r0 ⊦ r0 = jvmref, r ≠ r0 ∧ (r0 -- sk ∈ st → r1 ≠ r0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
⊦ r -- _type ∈ addarray(r, ty, i, st)
Proof step 5:
r0 ∈ st, r0 -- sk ∈ st, ∀ rk. rk ∈ addarray(r, ty, i, st) → rk .ref ≠ r0 ⊦ r = r0, r0 = jvmref
