// 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.
