そうですね．もっとも位置は変っても同じ名前を継承関係の中に残
しておいたりと，一応の互換性(意味がちょっと変ってるけど)は残
してます．

まあ，それはそうですね．

|[案1]
|1. 例外はExceptionのサブクラスだけに限定する.
|2. モジュールDefaultRescueもなくす.
|3. ExceptionはStringのサブクラスではなくする.

|[案2]
|1. Exceptionはなくす. まとまっている意味はあまりない.
|2. ExceptionはStringのサブクラスではなくする.
|3. StandardErrorをStandardExcptionに改名.

案1と案2を比べてみると案1の方が優れていると思います．

  * 単純で理解しやすい
  * Exceptionというクラスがなくなると変更する必要のあるスク
    リプトが増える(案1なら取り敢えず動くものが多数)

だからです．
