SBCL: Assembly code breadboard (2014)

I recently tried using the dynasm-rs crate as a dynamic assembler for a project, and it's also really nice to use. I think something like Lisp still probably wins in terms of usability, since you can do the fancy macro abuse over your assembly DSL, but dynasm-rs was great if you just want runtime code generation without parameterize over stack offsets or something else insane like the OP.
