+// C++0x [class.access]p6:
+//   All access controls in [class.access] affect the ability to
+//   access a class member name from a particular scope. For purposes
+//   of access control, the base-specifiers of a class and the
+//   definitions of class members that appear outside of the class
+//   definition are considered to be within the scope of that
+//   class. In particular, access controls apply as usual to member
+//   names accessed as part of a function return type, even though it
+//   is not possible to determine the access privileges of that use
+//   without first parsing the rest of the function
+//   declarator. Similarly, access control for implicit calls to the
+//   constructors, the conversion functions, or the destructor called
+//   to create and destroy a static data member is performed as if
+//   these calls appeared in the scope of the member's class.
