Proof step 11 from proof okarray-getbar-len (conclusion)

⊦ okarray(val, byte_type, n→i(n), st) → # getbytearray(val .refval, st) = n

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ okarray(val, ty, i, st) ↔ okarray(val .refval, ty, st) ∧ st[val .refval -- _length] .intval = i
Proof step 10:
⊦ okarray(val .refval, byte_type, st) ∧ st[val .refval -- _length] .intval = n→i(n) → # getbytearray(val .refval, st) = n
