      C.f should be "ok". But when have require the mongoid, the result is xxx. mongoid and activesupport I do not know either side of the issue. Please tell me if there is a workaround.

      gem "psych", "2.0.12"
require "psych"

gem "activesupport", "4.2.0"
require "active_support/core_ext/kernel/concern"

gem "mongoid", "4.0.1"
require "mongoid" if true       # <-- If false the result is ok

class B
  def self.f
    "xxx"
  end
end

concern :M do
  class_methods do
    self                        # => Mongoid::Extensions::Object::ClassMethods
    def f
      "ok"
    end
  end
end

class C < B
  include M
end

C.f                             # => "xxx"
