// 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.
