Below code will result into error:

~~~
super: no superclass method `foo' for #<Object:0x002b0430670fe8>
~~~

However, it can pass with Ruby 1.9 and I am not sure if it's feature changes or bug.

~~~ruby
module A
  def foo
    puts "A"
  end
end
 
module B
  def foo
    puts "B"
    super
  end
 ub_meth = instance_method :foo
  define_method :foo do
    ub_meth.bind(self).call()
 end
end
a = Object.new
a.extend A
a.extend B
a.foo
~~~
