Right, we are now properly rejecting this.

template_foo.cpp:31:15: error: no matching function for call to
'type_constructor'
    decltype( type_constructor( &Y::bar ) ) x(y);
              ^~~~~~~~~~~~~~~~
template_foo.cpp:18:6: note: candidate template ignored: substitution failure
[with T = Y]: non-type template
      argument of type 'void (Y::*const)()' is not a constant expression
auto type_constructor( void (T::* const f)() ) -> X< T, f >;
     ^                                                  ~
