Proof step 11 from proof isarray-addarray-other (previous step)

st[r -- _type] .type = mkarraytype(ty), r ∈ st, r -- _type ∈ st, is_typevalue(st[r -- _type]), is_array(r, st) ⊦ r = r0, okarray(r, ty, addarray(r0, ty0, vals, st)) ∧ r ≠ jvmref

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 10:
st[r -- _type] = typeval(ty1), ty1 = mkarraytype(ty), r ∈ st, r -- _type ∈ st, is_typevalue(st[r -- _type]), is_array(r, st) ⊦ r = r0, okarray(r, ty, addarray(r0, ty0, vals, st)) ∧ r ≠ jvmref
