Does this do what you want to do?

class Object
  def preextend m
    singleton_class.prepend m
  end
end

If yes, then there is no urgent need to ask for a new feature from the core team.

```
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?
