Proof step 7 from proof mkjavavalues-byte-lastrec (previous step)

is_bytevalue(val), ∀ val0. is_bytevalue(val0) → mkjavavalues(bytes0 + val0 .byteval ') = mkjavavalues(bytes0) + val0 ' ⊦ mkjavavalues(bytes0 + val .byteval ') = mkjavavalues(bytes0) + val '

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 6:
val = byteval(by), is_bytevalue(val), ∀ val0. is_bytevalue(val0) → mkjavavalues(bytes0 + val0 .byteval ') = mkjavavalues(bytes0) + val0 ' ⊦ mkjavavalues(bytes0 + by ') = mkjavavalues(bytes0) + val '

Rule argument
