The macro is currently set to 201510 following P0092R1. In Kona P0505R0 added constexpr in a few more places, which are only very minor changes. I don't think we need a new macro, so setting the value to 201703 seems appropriate.
Hmm, although this assumes nobody would implement the latter feature before the first. Both libstdc++ and libc++ have already implemented the P0092R1 changes, and VC++ doesn't seem to define any feature-test macros. _______________________________________________ Features mailing list [email protected] http://www.open-std.org/mailman/listinfo/features
