retoor/wren: Highly customized version of the wren programming language. It has all the modules that you would expect in a std library including http, websockets, sqlite3 and jinja-like templating engine. The idea is to make it suitable for web development. - wren

Bob Nystrom 9c663aa13c feat: implement NaN tagging for Value union and hoist bytecode/IP into locals in interpret loop

Switch Value from a struct with type/num/obj fields to a NaN-tagged uint64_t/double union, enabling faster type checks and unboxed numbers. Refactor all macros and accessors (IS_OBJ, AS_OBJ, AS_NUM, etc.) to work with the new representation. Hoist CallFrame pointer, instruction pointer, and bytecode array into local variables inside the interpret loop, updating them on frame push/pop. Enable NAN_TAGGING define and DEBUG_GC_STRESS in common.h. Update Xcode project to use c99 standard, pedantic warnings, and treat warnings as errors. Add benchmark/fib.txt with timing comparisons showing fib benchmark within 25% of Lua.
