Subject: [isocpp-lib] New issue: missing feature test macro for <span>
There is no feature test macro for std::span.
For the purposes of SD-6, I think we want two values: 201803L for the original addition of <span> by P0122R7 (Jacksonville, 2018) and then 201902L for the API changes from P1024R3 (Kona, 2019). The C++ working draft only needs the newer value.
Proposed resolution:
Add a row to [tab:support.ft] in [support.limits.general]:
__cpp_lib_span 201902L <span>
