By "constant" I meant an immutable data structure.

It sounds like you're trying to interoperate with a Java library that's very structured around OOP principles, and very hard to translate into idiomatic Clojure. My guess is that you wouldn't have the issues you mention in a pure Clojure solution. - James -- You received this message because you are subscribed to the Google Groups "Clojure" group.
