This wording is relative to N4928.
Modify [version.syn], header <version> synopsis, as indicated and replace the placeholder YYYYMM by the year and month of adoption of P2652R0:
[…] #define __cpp_lib_algorithm_iterator_requirements 202207L // also in <algorithm>, <numeric>, <memory> #define __cpp_lib_allocate_at_least
202106L // also in <memory> #define __cpp_lib_allocator_traits_is_always_equal 201411L // also in […] […]
[ 2023-03-22; Reflector poll ]
Set status to Tentatively Ready after seven votes in favour during reflector poll. But "if we don’t get the editors to do it for C++23 there doesn’t seem to be any point doing it."
In Issaquah, we just adopted P2652R0, forbidding user specialization of allocator_traits.It looks like we did not deem that worthy of a feature macro. However, it also changed the interface of the C++23 addition, allocate_at_least, which is covered by the macro __cpp_lib_allocate_at_least. I believe we should have updated that macro for this significant change in how that function is accessed (from free function to a member of allocator_traits). Unfortunately, there are no more meetings to process a comment to that effect, and I suspect this rises beyond the purview of an editorial change, although I live in hope (as the original paper left the value of the macro to the editor, although we approved existing working papers where that macro does have a value, i.e., status quo).
