Elixir in Elixir
summary
Shows that Elixir implements most of itself — a 78% in Elixir measurement using GitHub linguist — and demonstrates the concrete mechanics: macros run at compile time, quote/unquote produce and inject ASTs, literals that quote to themselves, and how to implement an if macro by emitting a case. Covers tools and tactics: Macro.expand, Macro.to_string, mex for full expansion, Code.eval_quoted, Macro.prewalk, tradeoffs like code bloat, hygiene, and when to prefer plain functions over macros.
