Subject: [ruby-dev:47605] [ruby-trunk - Feature #3753] value of def-expr


Issue #3753 has been updated by matz (Yukihiro Matsumoto).


Yes, I think Module#define_method should return a symbol as def statement does.

 RubyKaigi見てて思い出したのですが、def式はSymbolを返すようにしませんか?
 そうすると、
 
 class Foo
   private def foo()
     # ...
   end
 end
 
 などと書けるようになります。
