Proof step 5 from proof is_array-okbytearray (previous step)

okbytearray(r, st) ⊦ is_array(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)
Proof step 4:
⊦ ¬ is_array(r, st) → ¬ okarray(r, ty, st)

Rule argument

[crewrite-arg: okbytearray-01, F, [st, r] → [st, r]]
