PersistentQueue

java.lang.Object
- clojure.lang.Obj
- - clojure.lang.PersistentQueue

All Implemented Interfaces:

IMeta, IObj, IPersistentCollection, IPersistentList, IPersistentStack, Seqable, Sequential, java.lang.Iterable, java.util.Collection
```
public class PersistentQueue
extends Obj
implements IPersistentList, java.util.Collection
```
conses onto rear, peeks/pops from front See Okasaki's Batched Queues This differs in that it uses a PersistentArrayList as the rear, which is in-order, so no reversing or suspensions required for persistent use
