Rust doesn't have fast compile, and I think it's hard to argue that a language without TCO is a functional language. Recursion is a critical part of the functional paradigm.

Also, I think a lot of people are attracted to Go because it's very simple to learn and use. Rust with its borrow checker is definitely not simple to learn and use.

But it's true Rust has some functional features.

That simplicity comes at a cost. The cost is duplicate code, less strict error handling and the billion dollar mistake.

I know that some people downplay the importance of these things; I find that because Rust has strong guarantees in these areas it helps to reduce work, reduce bugs and increase confidence in the software.

And use 'cargo check' during Dev for faster compiles.

In Go, I agree. But that's not necessarily the case for all simple languages. Take ML, for example. It's a very small, easy-to-learn language with excellent abstraction features that make it easy to avoid duplicate code, as well as excellent static checking and error handling.

Unfortunately, ML lacks a comprehensive, modern standard library like Go has.
