Adding Reflection to C

Here is my proposal with a lot of similarities: https://www.open-std.org/JTC1/SC22/WG14/www/docs/n3212.pdf

BTF or DWARF info in principle contain the information needed, though working with them is cumbersome...

Been there… Pendantic nitpick: it's more akin to introspection, reflection would be self-modifying code.
