Cpp features blocked by version

Summary

This is a listing of C++ features that would be useful to have but can't yet use. The Feature column is the language or standard library feature (https://en.cppreference.com/w/cpp/compiler_support is a good reference). The Benefit column is what having this feature will allow to be done. The remaining three columns are for the minimum requirements for the feature to be available on each platform. The minimum requirements can be anything - Visual Studio version, compiler version, OS version, etc.
