Description Marek Polacek 2020-03-30 23:16:29 UTC 
Implement <https://eel.is/c++draft/diff.cpp17.class#2>:

template<class T>
struct A {
  A<T>();           // error: simple-template-id not allowed for constructor
  A(int);           // OK, injected-class-name used
  ~A<T>();          // error: simple-template-id not allowed for destructor
};

Note this is not a DR against C++17, the above is only ill-formed in C++20 onwards.
