Replaced ~583 occurrences of NULL with nullptr in 51 C++ source files, following modern C++11 best practices for improved type safety. Changes: - Converted all NULL to nullptr in src/ directory (51 files) - Preserved NULL in public C API headers (include/lua.h, src/auxiliary/lauxlib.h) - Zero semantic changes - pure mechanical text replacement Performance: - Baseline: 4.20s average - After nullptr: 4.26s average (5 runs: 4.48, 4.21, 4.37, 4.09, 4.15) - Target: ≤4.33s (3% tolerance) - Status: ✅ PASS - within tolerance Testing: - All tests passing: "final OK !!!" - Zero compilation errors or warnings - Full backward compatibility maintained Benefits: - Type-safe null pointer constant (compile-time type checking) - Eliminates NULL macro ambiguity (0 vs pointer) - Modern C++11 standard practice - Better overload resolution - Zero performance impact
