What made Julia so difficult to package? I'm genuinely curious. > ... because of how little they care about increasing the safety in the language (like Rust or Ada). I think it's a bit harsh to compare Julia to Rust on that front. Julia has completely different design goals. Compared to Rust's borrow checker and C++'s move semantics, Julia's immutability-by-default (+ clever compiler optimizations) gives a good trade off between performance, safety and ease of use. While Rust goes for safety + performance, Julia goes for performance + ease of use (respectively dynamicity). Nevertheless, I miss some features related to type driven development in Julia, which would improve safety: - A newtype idiom - Sum types - Explicit, type-checked interfaces : I actually would prefer something like C++20 concepts (a blacklist approach) to Rust's trait (or typeclasses, a whitelist approach), because it would be a better fit for Julia's design goals.
