--- Comment #6 from Jason Liam <jlame646 at gmail dot com> ---
This means that the code `template<class T> struct A {~A<T>(); };` is
ill-formed only with c++20 and onwards while the code `template<class T> st=
ruct
A {~A(); }; template<typename T> A<T>::~A<T>(){} ;` is ill-formed in all c++
versions including c++17.=
