Functional languages have other constructs (than objects) for modularity, such as ML functors. "Dependency injection" is basically a glorified name for "abstracting over things" and has been used for ages in functional languages.
Designing code to be easy to test also improves its modularity and maintainability.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
