+// 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.
