It's a good point.

LLMs have not been trained on Toit code as much as they have on Python or JS. No question about that. Without the Toit skills (https://github.com/toitlang/ai-instructions) LLMs used to be really bad. (They might be better now, but I never bothered to remove the skill files). From that point of view, Toit isn't a good choice.

On the other hand, Toit provides containers and a fast refresh-cycle. Both are godsends for AI agents: the containers make it so that the agent doesn't accidentally bring down the whole system when there is a bug, and the refresh cycle makes iterating on programs much faster. (Something I find agents to be really good at).

Fwiw, there isn't any clever metaprogramming in Toit.
