Clojurians Log v2

Hello, is there an idiomatic way to do function “type checking” during runtime with ghostwheel? Clojure spec documentation suggests, at a very shallow level, to just do pre and post conditions. ghostwheel’s >defn syntax already looks like these pre and post conditions and it seems like the kind of thing to expect, but I don’t see it in documentation, nor do I see it in behavior. Is this functionality indeed present, and if not, is there a workaround I could do for it?
