So you've got a transient vector of persistent vectors of numbers. The problem is your update-in! then calls assoc! on each level, but of course assoc! on the inner persistent vector fails. You either need to make the inner vectors transient (and then call persist! on them when you're done) or use assoc! only at the outer level. --Chouser http://joyofclojure.com/
