Proof step 10 from proof okfieldinits-class (previous step)

fv = sk × val, okfieldinits(class0, fv ' + fis0), ∀ class0, class, ty, fieldvar. okfieldinits(class0, fis0) ∧ mkfs(class, ty, fieldvar) ' ∈ fis0 .keys → class = class0 ⊦ class = class0, mkfs(class, ty, fieldvar) ' ≠ sk ∧ ¬ mkfs(class, ty, fieldvar) ' ∈ fis0 .keys

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 9:
okfieldinits(class0, (sk × val) ' + fis0), ∀ class0, class, ty, fieldvar. okfieldinits(class0, fis0) ∧ mkfs(class, ty, fieldvar) ' ∈ fis0 .keys → class = class0 ⊦ class = class0, mkfs(class, ty, fieldvar) ' ≠ sk ∧ ¬ mkfs(class, ty, fieldvar) ' ∈ fis0 .keys
