That's full of code. I think there is no problem with Domieszka.


module Domieszka

attr_accessor :x, :y


   def moveto(x,y)

         @x = x

         @y = y

         end

end


Circle = Struct.new(:x,:y,:r) do

   include Domieszka

   def field

   p = Math::PI * r**2

   end


   def field=(r)

   self.r = r

   end

   def obwod

   o = 2*Math::PI*r

   end

   def obwod=(r)

   self.r = r

   end

end


Square = Struct.new(:x,:y,:a) do

   include Domieszka

   def field

   p = a**2

   end

   def obwod

   o = 4*a

   end

   def field=(a)

   self.a = a

   end

   def obwod=(a)

   self.a = a

   end

end



class Rectangle<Square


   def fieldRect=(b)

   self.b = b
   end
   def fieldRect
   p=a*b

   end
end
