I seriously question why you ever want to do this in any language except as a research effort. (for all practical purposes)
If anyone has any real applications I would like to be enlightened. Writing an interpreter, hoping to sandbox it, executing it with modifying code with it does not count, only modifying the original program as is.

Instead, it reconfigures stock GCC and Clang to output a POSIX-approved polyglot format that runs natively on Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS with the best possible performance and the tiniest footprint imaginable.
