The cool thing about Rust is that at least you have powerful abstractions you can use. But the cool thing is that you can conveniently compose other no_std crates into your stuff. No more futzing about with m4 or global namespace collisions or did-they-leverage-some-weird-dependency-that-I-can't-build-here.
