Proof step 18 from proof exactarray-08 (previous step)

st[r -- _type] .type = mkarraytype(int_type), st[r -- _length] = intval(i), 0 ≤ i, r ∈ st, is_typevalue(st[r -- _type]), r -- _type ∈ st, is_integervalue(val), is_arrayref(r, i, st), r -- _length ∈ st ⊦ r = jvmref, exactarray(r, int_type, st[r0 -- j ', val])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 17:
st[r -- _type] = typeval(ty), ty = mkarraytype(int_type), st[r -- _length] = intval(i), 0 ≤ i, r ∈ st, is_typevalue(st[r -- _type]), r -- _type ∈ st, is_integervalue(val), is_arrayref(r, i, st), r -- _length ∈ st ⊦ r = jvmref, exactarray(r, int_type, st[r0 -- j ', val])
