Proof step 5 from proof isobj-all (previous step)

st[r -- _type] = typeval(mkclasstype(class)), r -- _type ∈ st, r ∈ st, ∀ sk. sk ∈ sks → goodfieldandtype(r, sk, st) ⊦ r = jvmref, goodfieldsandtypes(r, sks, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ goodfieldsandtypes(r, sks, st) ↔ (∀ sk. sk ∈ sks → goodfieldandtype(r, sk, st))
Proof step 4:
st[r -- _type] = typeval(mkclasstype(class)), r -- _type ∈ st, r ∈ st, ∀ sk. sk ∈ sks → goodfieldandtype(r, sk, st) ⊦ r = jvmref, ∀ sk. sk ∈ sks → goodfieldandtype(r, sk, st)
