Yes, I've realized that as well :-) I would have to maintain a Java

I looked at the source code. ImmutableSet doesn't support adding
adding or removing elements incrementally. You can make an
ImmutableSet.Builder from an existing ImmutableSet of n elements and
then make a batch of m updates from which it will construct a new
ImmutableSet in O(n+m) time. It simply i
It has nothing to do with Clojure but your colleague can look at the
Google collection library that contains an ImmutableSet.

As Clojure moves towards being self-hosted, fewer and fewer of the
data structures will be implemented in Java, thereby ensuring
dependence on the Clojure runtime. Just FYI.

Did you run the test with the -server jvm option? This command line
argument is usually recommended when measuring performance.

Hello,
a colleague of mine asked me a question about clojures set
implementation performance. He needed an immutable set on the jvm
platform for a Java/Scala project, and since I've been saying that
Clojures data structures have good performance he tried clojures set.
He was dissapointed though :-(
