Looking at the source for distinct, the reason it fails is because it tries to destructure the set as a seq, and sets can't be destructured in this way.
A lot of people think that (let [[f & r] coll] ...) is the same as (let [f (first coll), r (rest coll)]...), but they are not the same, because first and rest implicitly call seq, but destructuring does not. Perhaps this is an oversight in the clojure.core/distinct source. It's certainly an easy enough change (just change the destructuring line, or call seq on coll, or do something polymorphic for the case of sets) and then it would support sets as well. I couldn't speak to that. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
