I'm a big Rust fan too. I have experience in all of the languages you've mentioned, and I'm most productive in Rust as well.

It's funny you mention enums, there was just another thread last week where I brought up how crazy it is that sum types (Rust enums) and pattern matching have been around since the 70s but have largely been limited to the FP languages. After extensively using Rust for ~3 years now, I don't ever want to use a language without sum types - you can write incredibly expressive and concise code with them.

The other major productivity boost for me is the ability to compose and chain Iterators and mix those with collection types.

People often demand generics in Go. But I think that actual sum types would be a bigger boon (if I got to choose).

You can basically avoid interface{} in generic Go code with some copy and paste. But you can't really avoid it when you're trying to write code that would be cleaned up by an actual sum type.

Not to commit the predicable sin of comparing Rust to Go any time either is brought up. I just mean to +1 the idea that sum types should actually be a fundamental tool that we can reach for in every language. So weird that it's taking so long to go mainstream, so to speak.

I just implemented an iterator in rust yesterday. After having done it in c++ back in the day, I was blown away by how easy and powerful it is.
