Sean Griffin on type systems and hopes for Rust’s future Notes ——- Chris chats with Sean Griffin about the tradeoffs between mental overhead and type safety, the expressiveness of different type systems, and some of the places where Rust currently falls down. ### Corrigenda Sean noted he could be wrong about `IEnumerable` not having a `Sum` method in C♯, and post-show research indicated that he was (it’s possible it was added after he had stopped doing .NET work, of course). See the [documentation][c1] for details on how `IEnumerable.Sum` it behaves in C♯ if you’re curious. As a related note, I (Chris) have done a little bit of digging on C♯ in the interval and it’s fair to say that while a lot of the “ceremony” involved in writing C♯ is annoying, it’s much more than just a “slightly nicer Java”, and indeed is a much nicer language than my previous, limited exposure had led me to believe. It’s no Rust or F♯, but its type system is substantially more capable than Java’s. [c1]:…
