Build Your Own Elixir
summary
A working pipeline appears: source is tokenized with leex rules, parsed with yecc grammars into an AST, tiny linters and a Slim‑like templating compiler generate quoted Elixir code via macros, and a toy language named gleam compiles its AST into Core Erlang and loads with erl_compile/code:load_binary so it runs on the BEAM — one developer ends up with a 15th language on the platform and a working "Hello World" rather than just slides about syntax.
