Either we're talking at cross-purposes (it's possible: I'm rather unfamiliar with OOP terminology) or you're missing a lot about functional programming. Modules and abstraction (i.e. Interchangability) were basically invented in the functional language CLU.
The seminal papers on abstract types are James Morris's Protection in programming languages and Types are not sets. Later, most improvements in module systems and abstraction have come from the functional programming world, through ML-like languages.
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.
