Proof step 4 from proof switch-obj (previous step)

⊦ r = r0, addarray(r, vals, 0, addobj(r0, class, fis, st[r -- _type, typeval(mkarraytype(ty))][r -- _length, intval(n→i(# vals))])) = addobj(r0, class, fis, addarray(r, vals, 0, st[r -- _type, typeval(mkarraytype(ty))][r -- _length, intval(n→i(# vals))]))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ r ≠ r0 → addarray(r, vals, i, addobj(r0, class, fis, st)) = addobj(r0, class, fis, addarray(r, vals, i, st))

Rule argument

[crewrite-arg: switch-obj-01 , F , [st, fis, class, r0, i, vals, r] → [st[r -- _type, typeval(mkarraytype(ty))] [r -- _length, intval(n→i(# vals)) ], fis, class, r0, 0, vals, r] ]
