Hmm, I have to try out that extend-type trick to silence the warnings, although using defrecord for clojurescript and not for clojure would feel awkward as well. > In clojure, doing this will give you a compile-time error, meaning you have > to reimplement all the functionality of a defrecord using deftype, even for > protocols you do not actually want to override. > > The Potemkin library has some macros to make this kind of thing less tedious, > I recommend taking a look: https://github.com/ztellman/potemkin Oh, I'd had a look at Potemkin before in other context, but had forgotten it also has def-map-type which helps. I'll go look there for inspiration. In any case it looks like custom deftype and implementing map functionality on top of that would be the way to go. Thanks a lot for your help in clearing out things. Would still hope for the records to be a bit more extensible, having a typed map that can implement protocols and avoids lookups for fields is nice, but doesn't really bring that much benefits over plain maps and functions IMHO. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
