Frankly, I believe that the criteria for the language selection for throw-away code is just that:
> This certainly is in part because I’m more proficient in Rust than in Python. It’s also because the Rust mental model is closer to how my brain works than the Python one.
You'll be more productive in writing the quick dirty hacks in language and programming model that you're the most comfortable with. That's it, the rest is IMHO just an attempt to rationalize your intuitive feelings.
