Baby, bathwater. Making a persistent map out of a Java map is expensive. Not everything that implements Map is concrete; e.g., spending several seconds making a local persistent Clojure map out of a distributed hash table proxy, just to get a value, would cause programmers to drop down to Java to avoid this pointless restriction. Why bother? Shooting at targets gives you the opportunity to shoot yourself in the foot, and that's not a bad thing. If you want the guarantees of persistence, then by all means use persistent structures. Programming is the act of making these choices. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
