My general take (and w/ the caveat that every system is different) is as follows:
- procedural code to enter into the system (and perhaps that's all you need)
- object oriented code for domain modeling
- functional code for data structure transformations & some light custom control flow implementation (but not too much)
I like the imperative shell, functional core pattern quite a bit, and focusing on data structures is great advice as well. The anti-OO trend in the industry has been richly earned by the OO architecture astronauts[1], but the idea of gathering a data structure and the operations on that data structure in a single place, with data hiding, is a good one, particularly for domain modeling.
In general I think we are maturing as an industry, recognizing that various approaches have their strengths and weaknesses and a good software engineer can mix and match them when building a successful software project.
There is no silver bullet. If only someone had told us that years ago!
