But I find it hard to get excited about a records-only solution, mainly because I hardly ever use records. Using straight maps, sets, and vectors to represent data is perfectly ordinary and idiomatic in Clojure, e.g., Paul's initial code didn't use records to represent his objects. So solving the problem just for records doesn't feel to me like much of a solution. > I suspect we can duplicate the approach already taken by Scala for case > classes. > > > There are two things that jump out to me as things that might make it hard to mimic Scala's approach for case classes in Clojure's records: 1. Clojure records function like maps, and you can assoc more things into them after construction. Scala is working with a fixed number of fields at compile time. 2. Scala knows the type of each of the fields at compile time, and so (if I understand their approach correctly), they can compile a custom hashing function for the case class that leverages the types of all its components for maximum speed. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
