Issue #9526 has been updated by Boris Stitnicky.


Also for me, this is the expected behavior. `MyMod` is prepended before `Blah`, and therefore `Blah.new.method( :x )` is taken from `MyMod`. As soon as you perform `module MyMod; remove_method( :x ) end`, method `x` will be again taken from `Blah`.

----------------------------------------
Bug #9526: Method#owner returns wrong owner if using prepend.

----------------------------------------
rdoc indicates that Method#owner will return a class or module that defines a method.
http://www.ruby-doc.org/core-2.0/Method.html#method-i-owner

-------------------
module MyMod
  def x(y)
    super(y*y)
  end
end

class Blah
  def x(y)
    y + 1
  end
  prepend MyMod
end

Blah.new.method(:x).owner
\# => MyMod

--------------------

In this case, a class or module that defines a method is Blah.
So I think Blah.new.method(:x).owner should return Blah.
