Proof step 10 from proof add-notin (previous step)

∀ sk, r, class, st. sk = _type ∨ (addobj(r, class, fis0, st)[r -- sk]) = st[r -- sk] ∨ sk ∈ fis0 ⊦ sk = _type, (addobj(r, class, fv + fis0, st)[r -- sk]) = st[r -- sk], sk ∈ fv + fis0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ addobj(r, class1, fv ' + fis, st) = (addobj(r, class1, fis, st)[r -- fv .1, fv .2])
Proof step 9:
∀ sk, r, class, st. sk = _type ∨ (addobj(r, class, fis0, st)[r -- sk]) = st[r -- sk] ∨ sk ∈ fis0 ⊦ sk = _type, ((sk = fv .1 ⊃ fv .2; addobj(r, class, fis0, st)[r -- sk])) = st[r -- sk], sk ∈ fv ', sk ∈ fis0
