The main thing is getting feedback. I've been doing some intense agent iteration on Lua projects, and so long as the error output is clear and it's easy for the harness to restart/inspect/stream logs it seems to do very well with Lua

In fact, I'd say it's more "fun" watching an agent work on something in Lua as the iteration loop is tighter: more restarts, more feedback, instant running. When I deal with typed languages (in my case, Swift) the feedback loop is dragged-out by the compile time which makes the whole process feel slower
