A lot of these issues can be fixed. Adding robust type constraints (e.g. traits) and accompanying "static analysis" tooling would help a lot. Julia can learn a lot from ML-family languages (e.g. OCaml, Haskell) in that regard. And there are efforts in the Julia community to add these features via third-party libraries. However, I don't see things improving unless such features are baked into the language and used more ubiquitously in open source modules.
