Proof step 4 from proof ao-put (previous step)

⊦ r = r0, (addobj(r, class1, [], st)[r0 -- sk, val]) = addobj(r, class1, [], st[r0 -- sk, val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ addobj(r, class1, [], st) = st[r -- _type, typeval(mkclasstype(class1))]
Proof step 3:
⊦ r = r0, (st[r -- _type, typeval(mkclasstype(class1))][r0 -- sk, val]) = (st[r0 -- sk, val][r -- _type, typeval(mkclasstype(class1))])

Rule argument
