             Bug #: 13210
           Summary: Provide better diagnostics for the case where a
                    template class name is used without the template
                    argument

            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++

template <class T>
class C{};

void f() {
  new C();
}
ehsanakhgari:/tmp [10:02:23]$ clang++ -c test.cpp 
test.cpp:5:7: error: expected a type
  new C();
      ^
1 error generated.

We could indicate that C is a template class name, and requires a template
argument.
