YARD has @option:

   class Test
     # Nice little method with hash-arg
     #
     # @option param :height [Fixnum, #to_i] (300) The height
     # @option param :width  [Fixnum, #to_i] (200) The width
     #
     def test(param = {})

     end
   end

I thing param:: an such was used by the Merb team.
