Proof step 31 from proof okarray-okarray-01 (conclusion)

⊦ okarray(val, ty, i, st) ↔ okarray(val .refval, ty, st) ∧ st[val .refval -- _length] .intval = i

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ is_referencevalue(val) → ¬ okarray(val, ty, i, st)
Proof step 2:
⊦ ¬ okarray(jvmref, ty, st)
Proof step 30:
val = refval(r) ∧ is_referencevalue(val) ⊦ okarray(val, ty, i, st) ↔ okarray(r, ty, st) ∧ st[r -- _length] .intval = i
