Re: Dynamically creating defrecord

Hi Sven, I was trying to do the same with my library tangrammer/defrecord-wrapper and, just today, I found a couple of links that worked fine for that http://grokbase.com/t/gg/clojure/11cjvz1jda/defrecord-based-on-runtime-metadata http://stackove

Re: Dynamically creating defrecord

Did you find something really wrong with defstruct? Occasions when the basis fields are not known to the programmer seem better met by defstruct than defrecord. And defstruct has *not* been deprecated in the API documentation. The comment "Note: Most uses of StructMaps would now be better se
