Class_lookup_helper::Class_lookup_helper (    )  [protected]

Helper class to implement lookup of class members. 10.2: First, every declaration for the name in the class and in each of its base class sub-objects is considered. A member name f in one sub-object B hides a member name f in a sub-object A if A is a base class sub-object of B. Any declarations that are so hidden are eliminated from consideration. Each of these declarations that was introduced by a using-declaration is considered to be from each sub-object of C that is of the type containing the declara-tion designated by the using-declaration.96) If the resulting set of declarations are not all from sub-objects of the same type, or the set has a nonstatic member and includes members from distinct sub-objects, there is an ambiguity and the program is ill-formed. Otherwise that set is the result of the lookup. FIXME: g++ accepts the following: struct A { struct stat {}; }; struct B { static void stat(); }; struct C : A, B { }; struct C::stat x; and rejects void x() { C::stat(); } We currently reject both.
