Potentially misleading yes, incorrect no. If you call send on an object you get an object back. It may be the same object, it may be another object. You could say 

obj.send(symbol [, args...]) → otherobj

Which would work for your case, but not if the object itself was returned. Take for example:

class Klass
	def test
	  self
  end
end

k = Klass.new
puts (k.send :test).class

--output:--
Klass
