I am taking up a discussion from 2010: https://groups.google.com/group/clojure/browse_frm/thread/60dff89149c3d2e6/
I would prefer if it would be possible to define "closed maps", e.g. maps that allow only a certain set of keywords, both for get and "set" (like in assoc, assoc-in, update-in, ...). It would be nice if there would be an option on defrecord to mark the map as "closed". I imagine that this would have some runtime penalty, because for every access it has to be verified if the key is a valid one. I understand that. Perhaps in that case the language could react differently based on the value of a dynamic var (*check-closed-defrecrod-p*) that can be set when the unit tests are run and could be false by default. I guess this topic was already discussed several times. Could somebody point me to previous discussions and their outcome? I've found in addition the following thread where the idea of "safe maps" was discussed to some extent: https://groups.google.com/group/clojure/browse_frm/thread/134642cc76de17f7/ Thanks, Christian -- You received this message because you are subscribed to the Google Groups "Clojure" group.
