Proof step 2 from proof addobj-addarray-switch (previous step)

⊦ r = r0, addobj(r, class, fis, addarray(r0, ty, vals, st)) = addarray(r0, ty, vals, addobj(r, class, fis, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ r ≠ r0 → addarray(r, ty, vals, addobj(r0, class, fis, st)) = addobj(r0, class, fis, addarray(r, ty, vals, st))

Rule argument

[crewrite-arg: switch-obj , F , [st, fis, class, r0, vals, ty, r] → [st, fis, class, r, vals, ty, r0] ]
