Proof step 4 from proof addbar-okarray-03 (previous step)

okarray(refval(r), byte_type, (addbytearray(r, ints, st)[r -- _length]) .intval, addbytearray(r, ints, st)) ⊦ (addbytearray(r, ints, st)[r -- _length]) .intval = n→i(# ints), r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ addbytearray(r, ints, st) = addarray(r, byte_type, mkjavavalues(is2bs(ints)), st)
Proof step 3:
⊦ (addarray(r, ty, vals, st)[r -- _length]) = intval(n→i(# vals))

Rule argument

[crewrite-arg: addbytearray-ints, F, [st, ints, r] → [st, ints, r]]
