Getting the name of a class that's in a module

ruby-talk

'some_object.class.to_s' doesn't work because it returns the entire hierarchy, i.e 'SomeModule::SomeClass'. I could do some string ops on that but it seems there would be an easier way. Here's an example:

class MenuStyle
   class Button < Style
   end
end

class View
   def initialize()
     @delegate = MenuStyle.const_get( self.class.to_s )
   end
end

Thanks,
Mike
