Hi. I'm very new to Clojure, but I've read most of the functional programming tutorial <http://java.ociweb.com/mark/clojure/article.html>.
Suppose I have a data structure called "node" that can be in one of a number of different states -- namely, "down", "waiting", and "running". Suppose that in the "running" state, the node has a "job-id" number associated with it, but such a number is not applicable in the other two states. Should I add an extra field, and only check that field in the "running" state, like so... (defstruct node :state :job-id) Or is there some better, or more "clojure-ish", way to approach this? If I was doing this in Haskell, I think that I would perhaps make some kind of algebraic "NodeState" data type, and have the JobId only attached to the Running constructor. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
