Rationale (November, 2014):

A type-id is intended as a reference to a type, but the opaque enumeration syntax is intended as a declaration, not a reference like an elaborated-type-specifier, so the current rules are as intended.

The grammar does not allow for a declaration of the form

  using T = enum class E : int;

However, it is widely accepted by current implementations. Should the rules be changed to accommodate this usage?
