I was debugging with inspect-tree and noticed that it errors when it
encounters a set (it thinks it's not atomic, but then nth produces an
UnsupportedOperationException).
I made a small patch (below) that makes inspect-tree work on
java.util.Sets, and also anything else that implements
clojure.lang.Seqable. If this is of interest, please let me know and
I can create an issue.
Cheers,
Jason
