Proof step 27 from proof ac-okarrays (conclusion)

⊦ r ≠ jvmref → (okarrays(r, fis, addclass(class, fis0, st)) ↔ okarrays(r, fis, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ okarrays(r, fis, st) ↔ (∀ sk, val. sk × val ∈ fis → is_integervalue(val) ∧ is_fskey(sk) ∧ is_arraytype(sk .fs .type) ∧ okarray(st[r -- sk], sk .fs .type .type, val .intval, st))
Proof step 26:
⊦ r ≠ jvmref → ( (∀ sk, val. sk × val ∈ fis → is_integervalue(val) ∧ is_fskey(sk) ∧ is_arraytype(sk .fs .type) ∧ okarray(addclass(class, fis0, st)[r -- sk], sk .fs .type .type, val .intval, addclass(class, fis0, st))) ↔ okarrays(r, fis, st))
