Ask HN: Why do you use Rust, when D is available?

D supports Ownership and Borrowing, just like Rust. DMD, D's reference compiler, can compile itself in less than 5 seconds, thanks to a fast frontend and fast backend. D is easy to metaprogram through traits and templates. You can make your own JIT in D with dynamicCompile.

I'd love to hear some reasons why so D and Rust can learn from each other.
