Yes, and typing will help towards AOT compiling and performance, etc., but I would really like to just dive in and write code in a language I already use or that can be shared among engines (there is a lot of Lua code out there in the game dev universe, for instance).

Having to learn another language (no matter how simple) for a specific runtime is the sort of time investment one should ponder carefully (I’ve written code in dozens of languages, and the learning curve until being productive matters a lot when you move across environments, frameworks and runtimes).
