And obtained the following new goals

Proof step 13:
⊦ fis .keys = statfields(class) ∧ okfieldinits(class, fis) ∧ compat(str, val, ty, st) → compat(str, val, ty, addclass(class, fis, st))
Proof step 14:
⊦ fis .keys = statfields(class) ∧ okfieldinits(class, fis) ∧ compat(str, val, ty, st) → compat(str, val, ty, addclass(class, fis, st))
Proof step 15:
⊦ fis .keys = statfields(class) ∧ okfieldinits(class, fis) ∧ compat(str, val, ty, st) → compat(str, val, ty, addclass(class, fis, st))
