Proof step 11 from proof add-update-same (previous step)

⊦ update(r, fis, addobj(r, class, [], st)) = addobj(r, class, fis + [], st)

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 10:
⊦ update(r, fis, st[r -- _type, typeval(mkclasstype(class))]) = addobj(r, class, fis, st)

Rule argument

[emptyarg]
