P3287R0: Exploration of namespaces for std::simd
2024-06-26 Library Evolution St. Louis Meeting Minutes
Champion: Lewis Baker Chair: Robert/Ben Minute Taker: Eddie
Summary
POLL: We should introduce a std::simd namespace in P1928 (realizing that this would mean we potentially have a type whose fully-qualified name is std::simd::simd and would involve removing “simd” from basic_simdmask) and remove the “simd” prefix from utilities moved into that namespace which currently have that prefix.

POLL: Element-wise overloads of existing functions in std which operate on std::simd::simd should also be available in the namespace std.
