Proof step 7 from proof okarrays-one-01 (previous step)

⊦ okarrays(r, (sk × val) ', st) ↔ is_integervalue(val) ∧ ¬ is_indexkey(sk) ∧ is_arraytype(sk .fs .type) ∧ okarray(st[r -- sk], sk .fs .type .type, val .intval, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 6:
sk .fs = mkfs(class, ty, fieldvar) ⊦ okarrays(r, (sk × val) ', st) ↔ is_integervalue(val) ∧ ¬ is_indexkey(sk) ∧ is_arraytype(ty) ∧ okarray(st[r -- sk], ty .type, val .intval, st)

Rule argument

[speclemmaarg: , class = fs .class ∧ ty = fs .type ∧ fieldvar = fs .field ↔ fs = mkfs(class, ty, fieldvar) ,[fs, class, ty, fieldvar] → [sk .fs, class, ty, fieldvar] ,T ,fieldspec , ,elim ]
