F# is quite usable with AI. All AI models are perfectly capable of generating idiomatic F# code. In fact, because it has a nice type system, if you ask the AI to model the problem well with types before implementing, hallucinated bugs are also easier caught.
Same with Nim. It works surprisingly well with AI tools. I think both have more straightforward syntax so it’s easy to generate. I’m curious how more complex languages do like C++ / Rust.
Last time I tried C++ with Copilot it was terrible.
