Proof step 21 from proof okarray-addarray (previous step)

0 ≤ j, j < n→i(# vals) ⊦ r = jvmref, vals = [], okval(vals[i→n(j)], ty), vals[i→n(j)] ∈ vals

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 17:
⊦ m < # vals → (¬ vals[m] ∈ vals ↔ false)
Proof step 20:
¬ i→n(j) < # vals, 0 ≤ j, j < n→i(# vals) ⊦ r = jvmref, vals = [], okval(vals[i→n(j)], ty), vals[i→n(j)] ∈ vals
