Proof step 5 from proof all-classes (previous step)

∃ class. ∀ r, ty, fieldvar. ¬ r -- mkfs(class, ty, fieldvar) ' ∈ st .keys, ∀ class. ∃ r, ty, fieldvar. r -- mkfs(class, ty, fieldvar) ' ∈ st ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
∀ class. ∃ r, ty, fieldvar. r -- mkfs(class, ty, fieldvar) ' ∈ st, ∀ r, ty, fieldvar. ¬ r -- mkfs(class, ty, fieldvar) ' ∈ st .keys ⊦
