Perhaps another avenue to get this feature without double the changes is metaclasses (Reflection).   They would enable classes with automatic getters/setters (for those who want them), or serialization or ensuring regularity (rule-of-#) or new defaults (like constexpr).   Then a function qualifier could be made a default for all members of a class.   -----Ursprüngliche Nachricht----- Von:Jens Maurer via Std-Proposals <std-proposals_at_[hidden]> Gesendet:Fr 22.05.2026 10:30 Betreff:Re: [std-proposals] Floating idea: grouping common function qualifiers to reduce syntactic repetition An:std-proposals_at_[hidden]; CC:Jens Maurer <jens.maurer_at_[hidden]>; On 5/22/26 10:20, Daniel Petrovic via Std-Proposals wrote: > *Open questions / concerns* > >   * Which qualifiers would be eligible?

For the other qualifiers, there is either a common code style recommendation not to use them excessively (noexcept) or a meaningful variation within a class where a scope-like grouping doesn't seem to be desirable (const, virtual). Is there an opt-out planned?  ("all member functions in this class are constexpr, except this one") You could gather some indication of usefulness by checking how existing code would benefit.  Start with the standard library. I think you'll find plenty of examples for "constexpr an entire class", but zero examples for the other keywords.
