It's not pretty, probably because the idea is based on Perl experience:

module MM
   def x
     @x_value ||= 100
     redefine_x
     x
   end

   def x=(xx)
     @x_value = xx
   end

   private

   def redefine_x
     class << self
       def x
         @x_value += 1
       end
     end
   end
end
