      class Module

- ¶

  Extend the base object itself like a static method

        @extends: (obj) ->
          for key, value of obj when key not in moduleKeywords
            @[key] = value

          obj.extended?.apply(@)
          @

- ¶

  Include methods on the object prototype

        @includes: (obj) ->
          for key, value of obj when key not in moduleKeywords

- ¶

  Assign properties to the prototype

            @::[key] = value

          obj.included?.apply(@)
          @

- ¶

  Add methods on this prototype that point to another method on another object's prototype.

        @delegate: (args...) ->
          target = args.pop()
          @::[source] = target::[source] for source in args

- ¶

  Create an alias for a function

        @aliasFunction: (to, from) ->
          @::[to] = (args...) => @::[from].apply @, args

- ¶

  Create an alias for a property

        @aliasProperty: (to, from) ->
          Object.defineProperty @::, to,
            get: -> @[from]
            set: (val) -> @[from] = val

- ¶

  Execute a function in the context of the object, and pass a reference to the object's prototype.

        @included: (func) -> func.call @, @::
