Proof step 10 from proof byteval (previous step)

i0 ≤ j, i + j < st[r -- _length] .intval, okarray(r, byte_type, st), 0 ≤ i + i0, r ∈ st ⊦ byteval(st[r -- (i + i0) '] .byteval) = st[r -- (i + i0) '], r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
is_bytevalue(val) ⊦ byteval(val .byteval) = val
Proof step 9:
¬ is_bytevalue(st[r -- (i + i0) ']), i0 ≤ j, i + j < st[r -- _length] .intval, okarray(r, byte_type, st), 0 ≤ i + i0, r ∈ st ⊦ byteval(st[r -- (i + i0) '] .byteval) = st[r -- (i + i0) '], r = jvmref
