Feature #4254: Allow method transplanting
http://redmine.ruby-lang.org/issues/show/4254

Author: Jonas Pfenniger
Status: Open, Priority: Normal
Category: core, Target version: 1.9.3

Is there a technical reason to not allow re-binding a method from one mod=
ule to any other module ?

  module M
    def foo; "foo"; end
  end

  module N; end
  N.send(:define_method, :foo, M.instance_method(:foo)) #=3D> should not =
raise

It's like monkey-patching. Powerful, dangerous, but also really useful. I=
t could allow different variations of method_wrap or alias_method_chain t=
hat are not possible right now.
