Scripting at the Speed of Thought: Lua and C++ with sol3
summary
A C++ binding library that replaces tuple-heavy compile‑time plumbing with a runtime-backed registry, sol2/sol3 exposes C++ classes as Lua usertypes with automatic overloading, container and pointer support and a sol::reference ARC type, plus convenience stack::push/get/check helpers and proxy conversions. The new usertype storage drops about 15% less compile time in tests, runs benchmarks against 13 libraries and matches sol2 performance while improving inheritance lookups and interoperating with other binders like Kaguya.
