SYMPTOMS
========

A using declaration causes the following error:

  error C2327: 'B::A::T2' : member from enclosing class is not a type name,
  static, or enumerator

CAUSE
=====

The name specified in a using declaration has the same name as an identifier in
the template argument list of a templated class.

RESOLUTION
==========

Modify the name in the using declaration or modify the name of the identifier in
the template argument list (see sample code below).

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

This problem was corrected in Microsoft Visual C++ .NET.

MORE INFORMATION
================

Sample Code
-----------

     // Sample Code that causes the error.

     template <class T1> struct A {
     int x;
     T1 y;
     int T2;
     };

     template <class T2> struct B : A<T2> {
     using A<T2>::T2;
     };

     // Sample Code that works around the error by changing the template
     // argument list.

     template <class T1> struct A {
     int x;
     T1 y;
     int T2;
     };

     template <class T3> struct B : A<T3> {
     using A<T3>::T2;
     };
