      By contrast, I rather default to open membership, offer matching constructs that support overlap, and permit reusing ctors across types.

      I think the claim that we should all switch to OCaml polymorphic variants is pretty different than not wanting sum types.

      I'm trying to counter claim that sum types = universal improvement. Go gets pretty far with second class products & memory-safe down-casting

      I'm a believer that less is generally more, even if it means choosing looser fitting primitives to avoid abundance of form-fitted ones.

      Reasonable people can disagree, but it's shortsighted to imply Go's designers were either ignorant or stupid, & Rust is somehow enlightened

      They weren’t stupid. They just made a design mistake. That’s OK. I made design mistakes with Rust too.

      My list of design complaints about Go is long. It just doesn't include lack of sum types.

      I'll think about everyone's complaints about Go while my Go code compiles. Oh, done. Time's up.

      My JS code compiles really fast too.

      Sure. And that's where Go did a good job balancing other aspects of the language. Fast compile isn't everything but it's significant.

      The lack of sum types has absolutely nothing to do with compilation time. It has everything to do with lack of optimizations.

          Not a big deal for the kinds of programs I write. Go's a good fit for me. I don't need a variety of types as interfaces suffice for the lot.

          I find that I define new interfaces relatively sparingly in applications. Although some occasionally have many implementations.
