In his book [Data-Oriented Programming - Unlearning Objects](https://www.manning.com/books/data-oriented-programming), the author Sharvit gives some guidelines for programming, which at first glance seem to be already baked in the Julia language like the separation of functions and data.

[Later it dawns you that each programming language has its own mantra, often tied to a specialty in its implementation, like Clojure’s immutable data structures relying heavily on dedicated [hashmaps](https://news.ycombinator.com/item?id=6445862).]

The book also recommends “generic data structures” to keep access simple and interfaces adaptable. In Julia this could be simple flat structs.  
In numerical textbooks using Julia structs barely play a role, here on Discourse they show up often in abstract MWExamples.

So I would like to hear your experiences on:

- Where did you need more complex (types, nesting, etc) structs?
- Was there a trade-off, did you find a balance or remedy?
