> You can cover literally the first two things with LuaJIT. Not at all. You don't have explicit control over generating machine code in LuaJIT. OTOH all Terra functions - whether dynamically generated or pre-written - will get compiled to machine code via LLVM. So it's explicit, i.e. more work, but more predictable. Arguably Terra code generation will cover more scenarios - consider some code paths may not be JITable at all by LuaJIT (due to NYI) but if you can generate a Terra function, you're guaranteed machine code. > If you're using Lua to not use Lua, you never wanted to use Lua to begin with! You're using Lua as a meta-programming language for Terra. If you know Lua, it could be a lot more convenient than using custom or archaic meta-programming languages.
