Proof step 9 from proof okfieldinits-abstract (previous step)

okfieldinits(class, (sk × val) ' + fis0), mkfs(class, abstract_type, fieldvar) ' ∈ (sk × val) ' + fis0, ∀ class0, fieldvar0. ¬ okfieldinits(class0, fis0) ∨ ¬ mkfs(class0, abstract_type, fieldvar0) ' ∈ fis0 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ okfieldinits(class, (sk × val) ' + fis) ↔ is_fskey(sk) ∧ val = initial_value(sk .fs .type) ∧ sk .fs .class = class ∧ sk .fs .type ≠ abstract_type ∧ okfieldinits(class, fis)
Proof step 8:
is_fskey(sk) ∧ val = initial_value(sk .fs .type) ∧ sk .fs .class = class ∧ sk .fs .type ≠ abstract_type ∧ okfieldinits(class, fis0), mkfs(class, abstract_type, fieldvar) ' ∈ (sk × val) ' + fis0, ∀ class0, fieldvar0. ¬ okfieldinits(class0, fis0) ∨ ¬ mkfs(class0, abstract_type, fieldvar0) ' ∈ fis0 ⊦

Rule argument
