In the latter mode, accepting it is in > keeping with the resolution of DR 147. Naming the constructor (Clang > accepts the test case above in C++ 11 mode). That is, when 'A<T>::A' > nominates class template A the name is instead taken to name the ctor of A. The point is that since 'A<T>::A; names the constructor, it isn't a type, and so using 'typename' shouldn't be allowed.
