Crystal: Fast as C, Slick as Ruby
From this post, Crystal appears to have some of the things many people have been lusting after in Rust: sophisticated metaprogramming, fewer sigils, a bigger standard library, fibers&#x2F;coroutines&#x2F;whatever-they&#x27;re-called-now.<p>But it still has a GC :(. Rust has completely spoiled me with making it easy to minimize dynamic memory allocation and copies, and to know (almost always) deterministically when something will go away.<p>EDIT: I should also say that if you want to bash on Rust&#x27;s lack of these things, 3 out of the 4 items I cited have solutions being actively worked on (either at planning, RFC, or implementation phase). I don&#x27;t think Rust&#x27;s sigils are going away any time soon, but I have no idea how you&#x27;d do that and preserve semantics anyway.
