That seems to be the crux of it - I remember reading a post by Paul Graham where he said something similar about object oriented programming. His core thesis seemed to be that functional programming does a better job of organizing things than object-oriented programming does, and once you have the core of functional programming in place (closures, first-class functions, whatever the hell a "monad" is), you don't need object orientation any more. I've never gotten deep enough into pure functional programming to really see things this way, but I've gotten deep enough to at least understand why these pure FP guys might think that.
