Metaprogramming in Elixir is more than macros. Arguably the non-macro parts are more accessible, easier to understand and less potentially obfuscating so I typically recommend starting there. And yes, Chris’s book is great (first Elixir book I bought way back when).
Its also a testament to José’s original language design that the AST hasn’t fundamentally changed. Some changes to the metadata to support improvements to the overall developer experience but that’s about it.
