Proof step 27 from proof stsubset-addobj (previous step)

newref(r, st) ⊦ st ⊆ addobj(r, class1, fis, st0) ↔ st ⊆ st0, r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ st1 ⊆ st2 ↔ (∀ rk. rk ∈ st1 → rk ∈ st2 ∧ st1[rk] = st2[rk])
Proof step 26:
newref(r, st) ⊦ (∀ rk. rk ∈ st → rk ∈ addobj(r, class1, fis, st0) ∧ st[rk] = (addobj(r, class1, fis, st0)[rk])) ↔ st ⊆ st0, r = jvmref

Rule argument
