Elixir is for DOING Things
summary
Elixir and OTP internals get practical: everything in OTP is public so Kernel.SpecialForms, the code module and the new code:fragment for LSP are usable directly; NIFs let you extend the VM but prim_socket could have avoided a custom NIF in one real project. Tracing with match specs is production-ready and LLMs reliably write those specs and grep OTP source. Surprising facts: OTP has a 40‑year pedigree, WX GUI and a markdown parser ship with the runtime.
