+## Example
+
+```coq
+theorem Function.id_def : @id α = fun x => x := rfl
+
+/-! ## decidable -/
+
+protected alias ⟨Decidable.exists_not_of_not_forall, _⟩ := Decidable.not_forall
+
+/-! ## classical logic -/
+```
+
+- kind: theorem | symbolic_name: `Function.id_def` | Batteries/Logic.lean:17
+
+## Use
+
+Statement and proof are available both joined (`fact`) and split (`statement`, `proof`) for
+proof-term modeling, autoformalization, retrieval, and dependency analysis via `deps`.
