Thanks Justin. Exploring the options now, at least for the Student class, which only has to implement an interface. Given the requirements of the standard ways of using the MASON libs, it initially seemed to me that gen-class was my only option. It's clear now that there are other possibilities. Among other things, I didn't realize that interfaces could be used without gen-class. Sorting out what works, how to make the result as efficient as the gen-class version, etc. may take some time.
(I think we really need a book focused solely on Clojure-Java interoperability. It's a big topic, with lots of options, pitfalls, poorly documented elements, etc. I would almost say that about gen-class alone. I don't know that there's enough of a market for such a book that anyone will bother writing, it, though.)
