<pre>Consider the following example:
struct A {};
using T = const A;
struct B : T {
using T::T; // error: 'const A' is not a direct base of 'B'
};
int main() {
B b;
}
The code compiles in GCC and VC14.1 but not in Clang (any version).
Obviously T must name a class for 'using T::T' to work ([class.qual]/2.2), so
according to [class.name]/5 'const' should be ignored.
In addition, the error makes no sense - how can 'const A' be a class at all?</pre>
