Proof step 4 from proof okfieldinits-class (previous step)

fs = mkfs(class1, ty0, fieldvar0), okfieldinits(class1, fis0), mkfs(class, ty, fieldvar) ' ∈ fis0 .keys, ∀ class0, class, ty, fieldvar. okfieldinits(class0, fis0) ∧ mkfs(class, ty, fieldvar) ' ∈ fis0 .keys → class = class0 ⊦ class = class1, ty0 = abstract_type, mkfs(class, ty, fieldvar) = fs

And obtained the following new goals

Proof step 3:
okfieldinits(class1, fis0), mkfs(class, ty, fieldvar) ' ∈ fis0 .keys, ∀ class0, class, ty, fieldvar. okfieldinits(class0, fis0) ∧ mkfs(class, ty, fieldvar) ' ∈ fis0 .keys → class = class0 ⊦ class = class1, ty0 = abstract_type
