This works:

(set/map-invert (java.util.HashMap. {:foo :bar}))

This also works:

(set/map-invert [[:a 1] [:b 2]])

Even this works:

(set/map-invert ["a1" "b2"])
{\1 \a, \2 \b}

Any reducible coll of nth-able pairs will do. How far should we go with the spec for set/map-invert?

The first case is used in Datomic

@danielcompton I added some test helpers here: https://github.com/slipset/speculative/blob/master/src/speculative/test.cljc (`success?` and gentest, combined into this test util, also named gentest: https://github.com/slipset/speculative/blob/master/test/speculative/test_utils.cljc#L22)
