Description Yusuke Suzuki 2015-04-16 12:27:23 PDT 
In ES6, some functions are used as the method with the different names.

For example,

Map.protoytpe[Symbol.iterator] === Map.prototype.entries
Set.protoytpe[Symbol.iterator] === Set.prototype.values
Array.protoytpe[Symbol.iterator] === Array.prototype.values
%Arguments%[Symbol.iterator] === Array.prototype.values

And we dropp Arguments' iterator implementation and its method for @@iterator since now they use Array Iterator and Array.protoype.values.
