Proof step 28 from proof ac-init (previous step)

∀ class1, st. mkfs(class1, void_type, `initstate' .field) ' ∈ fis0 ∨ initdone(class1, addclass(class1, fis0, st)) ⊦ mkfs(fs .class, void_type, `initstate' .field) = fs, mkfs(fs .class, void_type, `initstate' .field) ' ∈ fis0, initdone(fs .class, addclass(fs .class, (fs ' × val) ' + fis0, st))

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 27:
fs = mkfs(class, ty, fieldvar), ∀ class1, st. mkfs(class1, void_type, `initstate' .field) ' ∈ fis0 ∨ initdone(class1, addclass(class1, fis0, st)) ⊦ mkfs(class, void_type, `initstate' .field) = fs, mkfs(class, void_type, `initstate' .field) ' ∈ fis0, initdone(class, addclass(class, (fs ' × val) ' + fis0, st))

Rule argument
