Proof step 16 from proof validreflist-rec (conclusion)

⊦ validreflist(str, val ' + vals, ty, st) ↔ is_referencevalue(val) ∧ validref(str, val .refval, ty, st) ∧ validreflist(str, vals, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ validreflist(str, vals, ty, st) ↔ (∀ val. val ∈ vals → is_referencevalue(val) ∧ validref(str, val .refval, ty, st))
Proof step 15:
⊦ (∀ val0. val0 ∈ val ' + vals → is_referencevalue(val0) ∧ validref(str, val0 .refval, ty, st)) ↔ is_referencevalue(val) ∧ validref(str, val .refval, ty, st) ∧ validreflist(str, vals, ty, st)

Rule argument

[crewrite-arg: validreflist-def , F , [st, ty, vals, str] → [st, ty, val ' + vals, str] ]
