これが原因らしい… 🔪 public typealias BilinearForm<V: VectorSpace> = BilinearMap<V, V, AsVectorSpace<V.CoeffRing>> extension BilinearForm: BilinearFormType where Domain: ProductSetType & VectorSpace, Domain.Left: VectorSpace, Domain.Left == Domain.Right, Domain.CoeffRing == Domain.Left.CoeffRing, Codomain == AsVectorSpace<Domain.CoeffRing> { }
