是否有可以覆盖的所有ruby运算符的列表？(不是那些不能!)

有没有办法让Ruby能够做到这样的事情？

class Plane
  @moved = 0
  @x = 0
  def x+=(v) # this is error
    @x += v
    @moved += 1
  end
  def to_s
    "moved #{@moved} times, current x is #{@x}"
  end
end

plane = Plane.new
plane.x += 5
plane.x += 10
puts plane.to_s # moved 2 times, current x is 15
