The point here is to have a separate language. Data interoperability is about having multiple languages, not having only one to rule the world.

I've done (limited) schema validation in Python. Schema exports reasonably well to EDN (it is just clojure after all). One can read EDN pretty well. I don't have a full-blown Clojure interpreter that would be necessary for arbitrary Schema, but I can handle the core types as well in Python (or random other language) as I could in Clojure/Clojurescript.
