--- Comment #6 from Arthur O'Dwyer <arthur.j.odwyer at gmail dot com> ---
Bug #119197 is related: it asks for `std::expected` to be marked [[nodiscard]].
Microsoft STL has marked their `std::expected`; and in the same commit they
marked all their exception types as well.

That is, Microsoft has adopted the direction given in jwakely's comment #3. I
think libstdc++ should follow suit (which would also fix bug #119197).
