Theorem: LO.FirstOrder.Semiformula.eval_rewrite (Logic/FirstOrder/Basic/Semantics/Semantics.lean)

State before:
n₂ : ℕ
L : Language
μ : Type v
μ₁ : Type v₁
μ₂ : Type v₂
M : Type w
s : Structure L M
n : ℕ
e : Fin n → M
e₂ : Fin n₂ → M
ε : μ → M
ε₂ : μ₂ → M
f : μ₁ → Semiterm L μ₂ n
p : Semiformula L μ₁ n
⊢ (Eval s e ε₂) ((Rew.rewrite f).hom p) ↔ (Eval s e fun x => Semiterm.val s e ε₂ (f x)) p
