Subject: [ruby-core:45835] [ruby-trunk - Feature #4254] Allow method transplanting


Issue #4254 has been updated by trans (Thomas Sawyer).


What prevents methods from being transplanted *from* a class?

Feature #4254: Allow method transplanting

=begin
Is there a technical reason to not allow re-binding a method from one module to any other module ?
 
  module M
    def foo; "foo"; end
  end

  module N; end
  N.send(:define_method, :foo, M.instance_method(:foo)) #=> should not raise
 
It's like monkey-patching. Powerful, dangerous, but also really useful. It could allow different variations of method_wrap or alias_method_chain that are not possible right now.
