@kubamracek -- if you don't mind having a look at this, I'm looking for thoughts/feedback on how we can address the "blockers":

- Assembly for Darwin x86_64 and how we avoid the ELF'isms (do we need to implement darwin-specific assembly for MachO?)
- Syscalls, testing, etc. -- whether we need to do anything special here for making it work on macOS.
