Well, `some' finds an element in a seq that satisfies the given
predicate, and seq'ing a map will get you a sequence of key/value
pairs. So, using a set as a predicate, you could test whether a given
key/value pair exists in a map:
(some #{[:barney "rubble"]} {:fred "flinstone" :barney "rubble"})
So it does work on maps, albeit not in the way you'd expect it to.
