Proof step 10 from proof addobj-union-rew (previous step)

newref(r0, st), newref(r0, st0) ⊦ r0 = jvmref, typeval(mkclasstype(class)) = (st ∪ addobj(r0, class, fis, st0))[r0 -- _type], _type ∈ fis

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
⊦ rk ∈ st0 → (st ∪ st0)[rk] = st0[rk]
Proof step 8:
⊦ r -- _type ∈ addobj(r, class1, fis, st)
Proof step 9:
¬ _type ∈ fis ⊦ (addobj(r, class1, fis, st)[r -- _type]) = typeval(mkclasstype(class1))
