Proof step 7 from proof nouninit-put-03 (previous step)

∀ class0. class0 ∈ claset → ¬ initundone(class0, st[r -- mkfs(class, ty, fieldvar) ', val]) ⊦ ∀ class. class ∈ claset → ¬ initundone(class, st), ty = void_type

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
class0 ∈ claset, initundone(class0, st), ∀ class0. class0 ∈ claset → ¬ initundone(class0, st[r -- mkfs(class, ty, fieldvar) ', val]) ⊦ claset = ∅, ty = void_type, # claset = 0

Rule argument
