--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This warns about the use of D within its own class body:
struct [[deprecated("D is bad mmmkay")]] D {
void f(const D&);
};
d.cc:2:18: warning: ‘D’ is deprecated [-Wdeprecated-declarations]
void f(const D&);
^
Surely member functions of a deprecated class should be able to refer to the
class, otherwise you can't even implement the API without warnings. And even if
users don't use the class, simply including the header will warn, because the
class refers to itself.
