> I personally haven't found Rust that difficult to prototype in

Rust is actually a pretty nice language for prototyping IMO. I agree with your take - Rust has many escape hatches you can use to develop quickly. Then when it comes time to clean up, it's obvious where the deficiencies are (look for all the clones and unwraps, etc)

Thank you. Some commenters seem to think a scripting language somehow reveals some deficiency in the core language. Reality: not all code is available at compile time. Many applications need some way to inject code without recompiling.
