What do you think of this? I wasn't happy when Cub was bought by another company. But Cub faces Target, Walmart and Amazon. I guess I should go to more farmers' markets. https://www.twincities.com/2019/05/17/hp-enterprise-to-buy-supercomputer-pioneer-cray/ They both have C++ compilers. I hope their future compiler(s) will support #pragma once. IIrc, Cray's compiler doesn't support that. And I hope they will support #import. I'm not sure if either of them support that at this time, but both GCC and Clang support #import as an extension. I use both #pragma once and #import with my software. I use #import though only in the closed source part of my code.
