手元の歴史書(ChangeLog)をひもとくと

 * クラス定数が導入されたのは1994/03/08です．この時は%変数名
   でした．名前は違いますが，挙動は今と同じです．

 * 定数の名前が大文字で始まるようになったのは1995/02/20です．
   この時にクラス名/モジュール名は定数になりました．

 * ローカル変数において代入が宣言の代わりをするようになった
   のは1995/06/08です．この時点でこのルールを定数にまで適用
   すれば，クラス変数が作れたかも知れません．

となっています．

|ラムをrubyで行なえるようにするためかな??

そうです．Eiffelは(言語仕様が)お気楽でないのが好きでないとこ
ろです．
