[nilput]

There isn't a killer argument, the project is in its infancy and i created it for experimentation, there are many directions that could be taken, if i were to go with a scripting language for something like a game engine or a similar C or C++ project that needs scripting i'd definitely go with Lua because of how popular and mature it is.

in terms of benchmarks alone languages with JIT compilers will definitely beat this, that's one possible direction to go with (there are great projects out there that make adding this capability potentially easier, MIR for example), another feature would be a C FFI rather than just a C API.
