Proof step 11 from proof okfieldinits-abstract (previous step)

∀ class, fieldvar. ¬ (okfieldinits(class, fis0) ∧ mkfs(class, abstract_type, fieldvar) ' ∈ fis0), okfieldinits(class, fv + fis0), mkfs(class, abstract_type, fieldvar) ' ∈ fv + fis0 ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
okfieldinits(class, fv ' + fis0), mkfs(class, abstract_type, fieldvar) ' ∈ fv ' + fis0, ∀ class0, fieldvar0. ¬ okfieldinits(class0, fis0) ∨ ¬ mkfs(class0, abstract_type, fieldvar0) ' ∈ fis0 ⊦

Rule argument
