// C++03 [namespace.udecl]p3:

// For the purpose of overload resolution, the functions which are
|
|
// introduced by a using-declaration into a derived class will be
|
|
// treated as though they were members of the derived class. In
|
|
// particular, the implicit this parameter shall be treated as if it
|
|
// were a pointer to the derived class rather than to the base
|
|
// class. This has no effect on the type of the function, and in all
|
|
// other respects the function remains a member of the base class.
