There's no way to achieve this in standard C. However with one non-standard trick we can get there in a fairly satisfying way. And I've tested out `clang` and `cl` for compilers, `clang` and `link` for linkers, and various combinations of optimizations and link time optimizations, and found that this non-standard trick continues to behave as expected across the board. I have yet to test this out on a Linux or Mac machine, or on an a machine with an architecture other than an ARM64, so the research on this technique isn't *finished* but it's looking *very good*.
