+//   A program that calls for default-initialization or value-initialization of
+//   an entity of reference type is illformed. If T is a cv-qualified type, the
+//   cv-unqualified version of T is used for these definitions of
+//   zero-initialization, default-initialization, and value-initialization.
+//
+// FIXME: The diagnostics for these errors are terrible because they fall out
+// of the AST representation rather than being explicitly issued during the
+// respective initialization forms.
