You can also define alternate constructors:

  class Point2D

    class << self

      def new_xy( x, y )
        new.set_xy( x, y )
      end

      def new_rt( r, t )
        new.set_rt( r, t )
      end

    end

    def set_xy( x, y )
      @x, @y = x, y
    end

    def set_rt( r, t )
      @r, @t = r, t
    end

  end

  p = Point2D.new_xy( x, y )
  p = Point2D.new_rt( R, theta )
