I am aware of edn-java; it has a very different scope than this library. edn-java is basically a pure Java implementation of an Edn parser, and it exposes the parsed data as mutable, untyped Java collections (e.g. an Edn map becomes a java.util.HashMap<?, ?>). I wanted to bring Clojure's entire data *philosophy *to Java: not just Edn, but also immutable persistent collections, metadata, and generic manipulation using functions like clojure.data/diff and clojure.core/merge.
At the same time, I wanted a way to put a typed facade in front of Clojure data, in order to prevent a lot of awkward unidiomatic downcasting; I also wanted a way for users to be able to validate, as a separate step, that these types are correct, instead of just getting a ClassCastException or NullPointerException further down the line. So you might say that I'm not just trying to replace JSON; I'm also trying to replace JavaBeans (or POJO's, or DTO's, or whatever you call them). Edn is a lot better than JSON, but Clojure data is *unbelievably *superior to traditional JavaBeans. You raise an interesting point about the relationship between tree-shaking and security. There is one place in the library where I'm using eval; I need it for defmethod, because the only alternative I'm aware of is MultiFn, which is an implementation detail. Were it not for that, it would be nice if dynamic-object could ship with a stripped-down version of Clojure that could avoid the entire security discussion.
