Proof step 8 from proof exactarray-length-01 (previous step)

st[r -- _type] .type = mkarraytype(ty), st[r -- _length] = intval(st[r -- _length] .intval), r -- _type ∈ st, is_typevalue(st[r -- _type]), r -- _length ∈ st, is_arrayref(r, st[r -- _length] .intval, st), r ∈ st ⊦ val2int(st[r -- _length]) = st[r -- _length] .intval, r = jvmref

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals
