Rationale (March, 2016):

Whether to support creating a temporary array in such cases is a question of language design and thus should be considered by EWG.

The intent is adequately expressed in the specification.

The current wording of the Standard appears to permit code like

  void f(const char (&)[10]);
  void g() {
    f("123");
    f({'a','b','c','\0'});
  }

creating a temporary array of ten elements and binding the parameter reference to it. This is controversial and should be reconsidered. (See issues 1058 and 1232.)
