I think the closest thing to "Rust plus green threads" isn't Go, but Haskell. If you try to switch from Rust to Go, you're going to find yourself missing the type system, ADTs, traits, etc.

I wrote this back in 2014 comparing (early) Rust, Go, and Haskell, but I think it's still more or less accurate. https://yager.io/programming/go.html

This misses the entire point of the article. The author's pain about Rust wasn't about wanting green threads - it was about building web APIs. Haskell doesn't succeed at that either. Haskell's Morpheus also suffers from n+1. Haskell isn't nearly as supported for the author's use cases as Python or Go, and Haskell is closer to Rust in that regard.

I'm addressing the comment I'm responding to. If I was responding to the contents of the article, and in particular the specific thing you're focusing on (GraphQL support) I would have written a different comment and posted it elsewhere in the thread.

hm I agree on the points made you made on the GoLang -- its design seem to be a regression. (to add another: look at Go's "default-value instead of Null" instead of adding actual null-safety in the type-system like kotlin/swift/scala/typescript/etc.)

Anyway, this blog-post seems to rally for a better eco-system work on Rust part. Being a new language without a rich parent (like Go's "google" or C#/Typescript's "MSFT"), the situation is somewhat understandable.

Yup! That's why Haskell is still the best language for business logic. Rust is for programmers at large companies trying to avoid the business (logic). I'm quite sympathetic, I would be doing that too at one of those. But when I need to program something a non-programmer actually cares about, Haskell is the way to go.
