One of my teachers liked to use the term value-oriented programming for the FP subset that does not make use of functions for data representations, or even first class functions beyond combinators like 'map'. I've always liked that term and that concept, and I do believe value-oriented programming, understood as programming with pure functions and simple values as much as possible, is 75% of the value of full functional programming. And I say that as someone who has both used Haskell as my primary language for over a decade, and implemented my own functional language.
