I find this a bit perplexing - it is possible to make organised, maintainable code without class-based polymorphism or statically enforced interfaces (traits, type classes). And Julia is so much easier than several other languages I know to organise your code in a neat modular way (and it still being quite generic and reusable).

Better static analysis tools (or traits/interfaces in the type system) would of course be welcome. But in my experience that’s more to catch silly mistakes and typos than to aid in healthy modularity or easy discoverability (which to me are remarkable good already).
