Sorry, that's not the same. I was setting the bar for adding an operator. Those have existed for some time as implementation-specific extensions, suc= h as=20 the Intel-defined intrinsics in (GCC and Clang) and =20 (ICC and MSVC). So like most of the standardisation coming from Boost, we get experimented = and=20 have found what works.
