//--------------------------------------------------------------------------------------
//ジェネリクスメソッドを先に公開し、それに特定の親クラスやインタフェースに特化した処理をさせたいという目的で
//もとのジェネリクスメソッドをオーバーロードする形でメソッドを実装してはならない

//オーバーロードメソッドを使用することができない。これは利用者に対して混乱を招く
//どうしてもやりたいなら、親クラス・インタフェース・継承するクラス・実装するクラス全てに対してオーバーロードメソッドを用意する
//そうすれば厳密に型一致するのでオーバーロードメソッドを利用できる
//実際の振る舞い
