Re: [boost] Boost.GSL?

The Guidelines document at https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md has added a FAQ: https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md... It addresses several of the issues and questions that had come up in this thread, so is worth a quick read if you care about the C++ Guidelines initiative. --Beman
