Would the attributes be applied to 'everything' or only to the respective entity type, e.g. [[nodiscard]] to functions only.   In the second case, where is it defined, which attribute is for what kind of entity?   There are standard attributes and custom attributes, e.g. by implementations, tooling.   And by the program: With reflection the code itself can read back attributes.   So it is observable, which entity gets the attribute.   -----Ursprüngliche Nachricht----- Von:Artur z Redy via Std-Proposals <std-proposals_at_[hidden]> Gesendet:Fr 29.11.2024 09:00 Betreff:[std-proposals] Proposal for policy scopes and attribute aliases in C++ An:std-proposals_at_[hidden]; CC:Artur z Redy <arturbac.ab_at_[hidden]>; I'm submitting a proposal for policy scopes and attribute aliases in C++ that aims to simplify attribute management across large codebases, particularly focusing on making error handling with std::expected safer by default while reducing maintenance overhead - I would greatly appreciate the review and feedback.  https://github.com/arturbac/policy_scope -- Std-Proposals mailing list Std-Proposals_at_[hidden] https://lists.isocpp.org/mailman/listinfo.cgi/std-proposals
