__callee__ in aliased methods defined in a module returns an incorrect value
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
With Ruby 2.3, instead of following snippet printing bar (as it does with ruby 2.2.4) it prints foo.
If the methods are defined within the class instead of an included module, the snippet prints bar.
module Mod def foo __callee__ end alias_method :bar, :foo end class Klass include Mod end a = Klass.new p a.bar
This appears to be the behavior for both 2.3.0 and ruby 2.3.0dev (2015-11-12 trunk 52550) [x86_64-linux]
