jank reimagines C++ errors and gets an official native package repo

jank, a Clojure dialect implemented on top of C++ and LLVM, has shipped major improvements to its error reporting: accurate stack traces for uncaught runtime exceptions that weave together AOT and JIT compiled frames with proper Clojure-level context, and dedicated error pages for each compiler error. The project also reimagines C++ compiler errors, rendering ambiguous overload candidates in a table format that's more readable than Clang or GCC output, including support for jank's own automatic trait conversions. Separately, jank now has a Cargo-inspired native build system built on top of Clojars, plus an official package repository called the jank commons that hosts '-sys' packages providing native library bindings, with an awesome-jank list for discovery. Other changes include a rewritten terminal REPL client with syntax highlighting and tab completion, optimized syntax-quote macro expansion, upstreamed LLVM/Clang fixes, and native value throwing support. The author is racing toward a talk at Clojure Conj 2026.
