2module ActiveSupport3  # A typical module looks like this:4  #5  #   module M6  #     def self.included(base)7  #       base.extend ClassMethods8  #       base.class_eval do9  #         scope :disabled, -> { where(disabled: true) }10  #       end11  #     end12  #13  #     module ClassMethods14  #       ...15  #     end16  #   end17  #18  # By using <tt>ActiveSupport::Concern</tt> the above module could instead be19  # written as:20  #21  #   require "active_support/concern"22  #23  #   module M24  #     extend ActiveSupport::Concern25  #26  #     included do27  #       scope :disabled, -> { where(disabled: true) }28  #     end29  #30  #     class_methods do31  #       ...32  #     end33  #   end34  #35  # Moreover, it gracefully handles module dependencies. Given a +Foo+ module36  # and a +Bar+ module which depends on the former, we would typically write the37  # following:38  #39  #   module Foo40  #     def self.included(base)41  #       base.class_eval do42  #         def self.method_injected_by_foo43  #           ...44  #         end45  #       end46  #     end47  #   end48  #49  #   module Bar50  #     def self.included(base)51  #       base.method_injected_by_foo52  #     end53  #   end54  #55  #   class Host56  #     include Foo # We need to include this dependency for Bar57  #     include Bar # Bar is the module that Host really needs58  #   end59  #60  # But why should +Host+ care about +Bar+'s dependencies, namely +Foo+? We61  # could try to hide these from +Host+ directly including +Foo+ in +Bar+:62  #63  #   module Bar64  #     include Foo65  #     def self.included(base)66  #       base.method_injected_by_foo67  #     end68  #   end69  #70  #   class Host71  #     include Bar72  #   end73  #74  # Unfortunately this won't work, since when +Foo+ is included, its <tt>base</tt>75  # is the +Bar+ module, not the +Host+ class.
