何度となく思ったジェネリックの制限

以下のようにかければ便利なのに。

private void ClearArray<T>(T[] array) where T : byte | char {

ポリモーフィズム的な制約に限らなくても new 制約みたいな考え方もある訳だしー

dynamic

が使えるので、似たようなコードを書こうと思えば書けるわけだけれど、遅延バインディングしまくりで例外エラーとか嫌だし、先頭で型チェックする感じになるのかなぁ。

でも、使用できるメンバのチェックはできないんだよなー

そういう風に書けても、結局メソッド本体で型ごとに分岐するコードになってあまりうれしくない気がする。
それより、where 制約の違いでオーバーロードしたいです。
