Nim Nuggets: Systems Programming & Metaprogramming Magic
summary
Fast compiler bootstraps from C in about 6 minutes and the Nim LSP builds from scratch in ~1 minute, enabling very quick feedback. The talk shows true compile‑time introspection (a macro that diffs two record types and generates a compile‑time migrate path), static resource management with destructor hooks and affine‑style sinks, and working C++ interop that uses std::vector/unique_ptr and emits a compile‑time factorial; demos run and are valgrind clean.
