Proof step 25 from proof validstatfields-addclass-other (previous step)

sk ∈ statfields(class0), ∀ sk. sk ∈ statfields(class0) → validstatfield(str, sk, st) ⊦ class = `java.lang.Object' .class, class = class0, validstatfield(str, sk, addclass(class, fis, st)), ¬ is_indexkey(sk) ∧ sk .fs .class ≠ class

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 24:
sk .fs = mkfs(class1, ty, fieldvar), sk ∈ statfields(class0), ∀ sk. sk ∈ statfields(class0) → validstatfield(str, sk, st) ⊦ class = `java.lang.Object' .class, class = class0, validstatfield(str, sk, addclass(class, fis, st)), ¬ is_indexkey(sk) ∧ class1 ≠ class

Rule argument

[speclemmaarg: , class = fs .class ∧ ty = fs .type ∧ fieldvar = fs .field ↔ fs = mkfs(class, ty, fieldvar) ,[fs, class, ty, fieldvar] → [sk .fs, class1, ty, fieldvar] ,T ,fieldspec , ,elim ]
