> Dean was doing an Erlang project so he asked “What example program would best exemplify Erlang“.<p>I wish such a canonical example was easy to find for every programming language, particularly those on the boundary between mainstream and exotic languages.<p>Most languages present themselves by waxing philosophical about HoTT, zero-cost abstractions, or parametric types. Show me an example where your language is <i>clearly</i> better than Python, Ruby, TypeScript, C#, or Rust, because those are the languages to beat, and they already have the entire infrastructure set up so unless you can demonstrably outperform them in <i>some</i> way, it's probably not worth my time to take a deeper look.
