It is an interesting feature, and possibly useful for Clojure, however
Clojure actually has few short-lived classes in a running program.
Functions are instances of classes, so calls to fn create a class once
and create instances many times, where normal GC applies. Programs
that do pervasive runtime eval would benefit most from this.
It is unlikely to be something I'd spend time on right now, as it
doesn't let you do anything new, and requires the latest-and-greatest
JVM.
