Proof step 9 from proof okarray-addarray (previous step)

n < # vals, is_arrayref(r, n→i(# vals), addarray(r, ty, vals, st)), ∀ j. ¬ j < 0 ∧ ¬ n→i(# vals) ≤ j → okval(addarray(r, ty, vals, st)[r -- j '], ty) ⊦ r = jvmref, vals = [], okval(vals[n], ty)

User applied rule all left

And obtained the following new goals

Proof step 8:
n < # vals, is_arrayref(r, n→i(# vals), addarray(r, ty, vals, st)), ¬ n→i(n) < 0 ∧ ¬ n→i(# vals) ≤ n→i(n) → okval(addarray(r, ty, vals, st)[r -- n→i(n) '], ty) ⊦ r = jvmref, vals = [], okval(vals[n], ty)
