> In general business problems that we deal with do not Require higher order functions. I cannot agree here, being currently involved in modeling and simulation work that would heavily benefit from more advanced type systems. A user would usually prefer to interact with a system with basic elements, but the interactions of the underlying domain concepts really do want to be captured with a richer set of tools. And, to head off the "in general", there is a long tail of unique problem domains. Each individually doesn't get as much press as, say, a CRUD app, but that doesn't mean that simpler problem domains are necessarily in the majority.
