∀ {R : Type u} {M : Type v} [inst : Semiring R] [inst_1 : AddCommMonoid M] [inst_2 : Module R M] [Module.Free R M]
  [StrongRankCondition R] {ι : Type u_2} (b : Module.Basis ι R M), Module.finrank R M = 1 → Nonempty (Unique ι)

If a finite module of finrank 1 has a basis, then this basis has a unique element.
