Data.Concurrent.Deque.Reference

A strawman implementation of concurrent Dequeues. This implementation is so simple that it also makes a good reference implementation for debugging.

The queue representation is simply an IORef containing a Data.Sequence.

Also see Data.Concurrent.Deque.Reference.DequeInstance. By convention a module of this name is also provided.

datadata SimpleDeque elt

Stores a size bound (if any) as well as a mutable Seq.
