Proof step 3 from proof new-insert-01 (conclusion)

⊦ newref(r0, st[r -- sk, val]) → r ≠ r0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ newref(r, st[r0 -- sk, val]) ↔ r ≠ r0 ∧ newref(r, st)
Proof step 2:
⊦ newref(r, st) ↔ r ≠ jvmref ∧ (∀ rk. rk ∈ st → rk .ref ≠ r)

Rule argument
