Description
check if a map contains all 3 keys with none unaccounted for
For any type of keys
(= #{:a :b :c "string-key"} (set (keys (select-keys m [:a :b :c]))))
as a function
(defn all-present? [keyset m] (assert (set? keyset)) (= keyset (set (keys (select-keys m keyset)))))
If there are only callable keys
(every-pred :a :b :c)
(every? m [:a :b "c" 1]) works but only for non-nil vals
(every? #(contains? m %) [:a :b :c]) if nil/false vals are OK, m as the predicate otherwise

Research direction
The issue names no file, test, or entry point. Review the proposed key-checking expressions and clarify whether the project should provide a reusable function for maps with arbitrary keys; done should include a decided behavior for nil and false values and coverage for the stated key types.
