We really don’t like the preprocessor, but it is currently necessary for many things, especially supporting different architectures, compilers, and Standard version modes. We regularly purge our implementation of no-longer-necessary macros, even when it breaks (non-Standard) code, as we recently did with `_NOEXCEPT`, and we look forward to removing even more. Please file an issue if you encounter macros that don’t appear to be necessary.
