Subject: [ruby-core:45168] [ruby-trunk - Feature #6452] Allow extend to override class methods


Issue #6452 has been updated by rosenfeld (Rodrigo Rosenfeld Rosas).


Yeah, sorry I should have thought about this before.

You're right, for normal usage the current behavior is more useful indeed.

I was willing to patch a class from a third-party library, that is why I wanted my module method to take precedence.

Would you consider to add a new method for such case? And an equivalent one for include as well?

Should I open a new ticket and close this one?

```
module A
  def self.a
    'a1'
  end
end

module B
  def a
    'a2'
  end

  def b
    'b'
  end
end

A.extend B

assert A.a == 'a2' # this is the change I'm proposing - currently it is 'a1'
assert A.b == 'b'
```

Would this change be possible for 3.0?
