"How to build a Clojure dialect"
summary
A Clojure dialect called Jank on LLVM targets native code with a C++ runtime and C++ interop, developed over seven years and rewritten multiple times. Implementation details: lexer evolved from regex to instaparse to a custom C++ tokenizer; parse tree is actual Clojure data so macros run as functions over that tree; runtime mixes interpretation, JIT and AOT compilation; interop uses native raw inline C++ with interpolation. Expect to reimplement hundreds of clojure.core defs and the Java-like object model as a C++ library.
