Proof step 22 from proof validstatfields-put-statfield-06 (previous step)

fs = mkfs(class1, ty, fieldvar), initdone(class, st), fs ' ∈ statfields(class), ∀ sk. sk ∈ statfields(class) → validstatfield(str, sk, st) ⊦ class0 = class1, class0 = class, mkfs(class0, void_type, `initstate' .field) = fs, validstatfield(str, fs ', st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 21:
initdone(class, st), mkfs(class1, ty, fieldvar) ' ∈ statfields(class), ∀ sk. sk ∈ statfields(class) → validstatfield(str, sk, st) ⊦ class0 = class1, class0 = class, validstatfield(str, mkfs(class1, ty, fieldvar) ', st)

Rule argument
