Proof step 8 from proof addarray-subset (previous step)

newref(r, st) ⊦ r = jvmref, st ⊆ addarray(r, ty, vals, st)

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 7:
newref(r, st) ⊦ r = jvmref, ∀ rk. rk ∈ st → rk ∈ addarray(r, ty, vals, st) ∧ st[rk] = (addarray(r, ty, vals, st)[rk])

Rule argument
