I’m guessing #ASM does the assembly at read or load time?

Does it desugar to something like this?

  (assemble ‘((mov rax %x) (add rax 1)))

Anyhow I think this is a great project. I hope you share it! I’ve often thought bootstrapping an assembler with lisp macros would be an interesting way to build a compiler from the very ground up. Assembler macros are nothing new, but I’ve never heard of an homoiconic implementation.
