Proof step 173 from proof compat-addclass (previous step)

fis .keys = statfields(class), compat(str, st), okfieldinits(class, fis) ⊦ compatmode(str, addclass(class, fis, st)) ∧ compatstatic(str, addclass(class, fis, st)) ∧ compatrefs(str, addclass(class, fis, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ compat(str, st) ↔ compatmode(str, st) ∧ compatstatic(str, st) ∧ compatrefs(str, st)
Proof step 172:
fis .keys = statfields(class), compatmode(str, st) ∧ compatstatic(str, st) ∧ compatrefs(str, st), okfieldinits(class, fis) ⊦ compatmode(str, addclass(class, fis, st)) ∧ compatstatic(str, addclass(class, fis, st)) ∧ compatrefs(str, addclass(class, fis, st))

Rule argument

[crewrite-arg: store-compat, F, [st, str] → [st, str]]
