Fri Oct 14 13:22:18 1994  Yukihiro Matsumoto  (matz@ix-02)

	* version 0.52: ……なんてこったい.

	* eval.c(rb_call): returnの処理が間違っていたので, マシンによって
	  はreturnで関数を終了するだけでなくtoplevelまでつき抜けていた.

	* object.c: Builtinクラスを新設. 組み込み関数をKernelから移した.
	  nilが組み込み関数を理解するとトラブルの元である.

	* dbm.c: Dictと同様にeachが[key,value]を返すように.
