If you look at this from an "expression problem" point of view, this version with the records-of-functions is very similar to OO programming. But without inheritance, classes and so on.
I'm very much a fan of that POV. I think OO has a lot of mythology, but the technology is relatively similar to something like OCaml or Haskell. Classes are essentially just functions which return "structures".
Inheritance and open-recursion/dynamic binding are usually what remain. I'm not terribly sure I miss them.
