pprint

Is there any way to make Clojure's pprint print the record tags for records? It seems odd to me that Clojure's main printer has evolved improved support for records over the years, but pprint still prints records as a plain, untagged map. -- You received this message because you are subscribed

Hi, There has been one thing bugging me for a long time that seems worth it to fix, and I was wondering if anyone else has had the same problem. I have enjoyed using Clojure's REPL and embracing a Clojure-style data model for my app, where everything is a glorified map or vector and there are

You might be interested in this ticket (http://dev.clojure.org/jira/browse/CLJ-1278) of which this is perhaps one special case. I don't know that I necessarily would want the equality semantics; at least in the case of impure functions the equality does not hold. On Friday, April 25, 2014
