Proof step 13 from proof validreflist-addarray (previous step)

validreflist(str, val ' + vals1, ty1, st), ∀ str, ty1, st, ty, vals0. validreflist(str, vals1, ty1, st) → validreflist(str, vals1, ty1, addarray(newref(st), ty, vals0, st)) ⊦ validreflist(str, val ' + vals1, ty1, addarray(newref(st), ty, vals0, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ validreflist(str, val ' + vals, ty, st) ↔ is_referencevalue(val) ∧ validref(str, val .refval, ty, st) ∧ validreflist(str, vals, ty, st)
Proof step 12:
is_referencevalue(val) ∧ validref(str, val .refval, ty1, st) ∧ validreflist(str, vals1, ty1, st), ∀ str, ty1, st, ty, vals0. validreflist(str, vals1, ty1, st) → validreflist(str, vals1, ty1, addarray(newref(st), ty, vals0, st)) ⊦ validreflist(str, val ' + vals1, ty1, addarray(newref(st), ty, vals0, st))

Rule argument

[crewrite-arg: validreflist-rec , F , [st, ty, vals, val, str] → [st, ty1, vals1, val, str] ]
