That said,\nif the change is approved, it would be really bad if the flag day\nwas postponed to GCC 16 -> 17 transition.\n\nThis patch doesn't add the annotations member and its handling, will\ndo that separately.\nOne disadvantage of this part of the paper is that ADL no longer works\nto find data_member_spec when one uses just\ndata_member_spec({.type=something,.name=something}).\n\n2026-03-25 Jakub Jelinek \n\nlibstdc++-v3/\n\t* include/std/meta (std::meta::data_member_options): Add\n\ttype member.\n\t(std::meta::data_member_spec): Remove info argument.\ngcc/cp/\n\t* metafns.gperf (enum metafn_kind_args): Add\n\tMETAFN_KIND_ARGS_DATA_MEMBER_OPTIONS and\n\tMETAFN_KIND_INFO_DATA_MEMBER_OPTIONS, remove\n\tMETAFN_KIND_ARGS_TINFO_DATA_MEMBER_OPTIONS and\n\tMETAFN_KIND_INFO_TINFO_DATA_MEMBER_OPTIONS.\n\t(data_member_spec): Use METAFN_KIND_INFO_DATA_MEMBER_OPTIONS\n\trather than METAFN_KIND_INFO_TINFO_DATA_MEMBER_OPTIONS.\n\t* reflect.cc (eval_data_member_spec): Remove type argument,\n\tread type from options.type.\n\t(process_metafunction): Adjust assertion for\n\tMETAFN_KIND_ARG_DATA_MEMBER_OPTIONS.
