@ambrosebs: I am getting this error: AssertionError Assert failed: (not (fr/NoFilter? f1)) clojure.core.typed.subtype/subtype-filter? (subtype.clj:1114) when checking something likes this: { :answer_id (id-correct params)} with stable latest core.typed. Is this a bug? There is no stacktrace or a "normal" type error returned, so I am a bit lost. Should I open an issue for it in JIRA?
