Proof step 5 from proof okarray-okarray-02 (previous step)

okarray(refval(r), ty, st[r -- _length] .intval, st) ⊦ r = jvmref, okarray(r, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ ¬ okarray(val .refval, ty, st) → ¬ okarray(val, ty, i, st)
Proof step 4:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st

Rule argument

[crewrite-arg: okarray-okarray , F , [st, i, ty, val] → [st, st[r -- _length] .intval, ty, refval(r)] ]
