Proof step 16 from proof ac-init-01 (previous step)

initundone(class, addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val]), ∀ class1, st. initundone(class1, addclass(class1, fis0, st)) → mkfs(class1, void_type, `initstate' .field) ' ∈ fis0, void_type ≠ ty ∨ `initstate' .field ≠ fieldvar ⊦ mkfs(class, void_type, `initstate' .field) ' ∈ fis0

User applied rule all left

And obtained the following new goals

Proof step 15:
initundone(class, addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val]), initundone(class, addclass(class, fis0, st)) → mkfs(class, void_type, `initstate' .field) ' ∈ fis0, void_type ≠ ty ∨ `initstate' .field ≠ fieldvar ⊦ mkfs(class, void_type, `initstate' .field) ' ∈ fis0

Rule argument

[EXRARG : pos: left 2, [extquanttermlist: (class, st) abort:F , discard:T , computed:F ]]
