----------------------------------------
It seems that optimized methods cannot overridden after `Module#prepend`.

```ruby
module M
  def /(other)
    quo(other)
  end
end
class Fixnum
  prepend M
end
module M
  def %(other)
    0
  end

  def foo
    puts "m#foo"
  end
end
p 1 / 2 #=> (1/2)  overridden
p 1 % 2 #=> 1      not overridden
1.foo   #=> m#foo  overridden
```

Is there any good way to disable optimization in this case?
