For me, Rust also fits "fun language to quickly prototype type system in", but I've been hacking in Rust since its 0.* days; if I were to try to do it in Ruby/Go which I've barely ever touched, it would sure take me way much longer.

If I were to compare Rust to Python/C++ which I'm proficient in, Python would be the fastest because there's zero setup time, tons of quality packages and notebook environment; C++ would take a lot longer due to having to set up builds, and due to lacking stdlib and ecosystem.
