+An object of type initializer_list<E> provides access to an array of
+objects of type const E[.](#1.sentence-1)

+[*Note [1](#note-1)*:
+
+A pair of pointers or a pointer plus
+a length would be obvious representations for initializer_list[.](#1.sentence-2)
+
+initializer_list is used to implement initializer lists as specified
+in [[dcl.init.list]](dcl.init.list "9.5.5 List-initialization")[.](#1.sentence-3)
+
+Copying an initializer_list does not copy the underlying
+elements[.](#1.sentence-4)
