erlangs bit matching syntax, case statements for structs... incredibly elegant. I don't know about Rust or Lua, maybe they have this too.

  Rust doesn’t have the bit matching syntax, but we do have match generally.

    It'd be interesting to explore something similar to the bitstring[1] library for Ocaml. Where should one start if exploring syntax extensions for Rust. I haven't looked into rust in a while now so i'm not sure how far one can get with macros these days. [1] https://github.com/xguerin/bitstring https://github.com/xguerin/bitstring

      “Macros 1.2” is what you want to look up; it’s in FCP right now!

  In particular, the elixir_ale library is a very pleasant interface to various bits of hardware you might want to interact with at the GPIO/i2c/etc level. https://github.com/fhunleth/elixir_ale https://github.com/fhunleth/elixir_ale

  MetaLua does!
