is there a way to use Malli to remove nil values in a map? :thinking_face:

The oddest thing. I have two projects. Both use malli 0.2.1 (according to `lein deps :tree`). But one of them accepts the syntax `[:map [:a string?] [:b string?]]` just fine, while the other throws an error on `(restart)`:

data-spec collection [] should be homogeneous, 3 values found

@lkorogodski Can you try with lein clean and then run your project again?

You might have some left-overs in your target folder or something

Same result.

@lkorogodski Please don't paste such long output into slack but rather use something like github gist

What happens when you do:

(require '[<http://clojure.java.io|clojure.java.io> :as io])
(io/resource "malli/core__init.class")

just checking if this isn't an AOT-related problem

Ok, sorry. Just a moment.

                                 :query  [:map
                                           [:a string?]
                                           [:b string?]}
                    ;; other things
                   }}]

map? works in place of [:map ...] but doesn't check enough, of course.
