// C++0x [basic.lookup.classref]p3:
//   If the unqualified-id is ~type-name, the type-name is looked up in the 
//   context of the entire postfix-expression. If the type T of the object 
//   expression is of a class type C, the type-name is also looked up in the 
//   scope of class C. At least one of the lookups shall find a name that 
//   refers to (possibly cv-qualified) T.
