            Bug ID: 31047
           Summary: Improve "x is not a class, namespace, or enumeration"
                    diagnostic. When x is a template class.
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend

    Classification: Unclassified

template<typename T>
struct Base {
  int foo();
};

template<typename T>
struct Derived : Base<T> {
  void bar();
};

template <typename T>
void Derived<T>::bar() {
  Base::foo();
}clang

Clang (-std=c++1z -fsyntax-only -Wall):

./test19.cpp:13:3: error: 'Base' is not a class, namespace, or enumeration
  Base::foo();
  ^
./test19.cpp:2:8: note: 'Base' declared here
struct Base {
       ^
1 error generated.

GCC (v6.2.1):

./test19.cpp: In member function ‘void Derived<T>::bar()’:
./test19.cpp:13:3: error: ‘template<class T> struct Base’ used without template
parameters
   Base::foo();
   ^~~~

It would be nice to have diagnostics like gcc which indicates that Base is
actually a template but it was used without template parameters.
