Proof step 5 from proof isarray-put-byte (previous step)

okbytearray(r0, st), is_array(r0, st) ⊦ is_array(r0, st[r0 -- i ', byteval(by)])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ is_array(r, st) ∧ okval(val, st[r -- _type] .type .type) → is_array(r, st[r -- i ', val])
Proof step 4:
¬ (is_array(r0, st) ∧ okval(byteval(by), st[r0 -- _type] .type .type)), okbytearray(r0, st), is_array(r0, st) ⊦ is_array(r0, st[r0 -- i ', byteval(by)])

Rule argument

[crewrite-arg: isarray-put-okval , F , [val, i, st, r] → [byteval(by), i, st, r0] ]
