| Description |
|
I've found it helpful to be able to iterate over ArrayChunks. Implementing Seqable means they can be used by most collections functions. |

2012-05-28 implements the seq method for vec and vector-of. It uses the array backing ArrayChunk to construct a sequence. Simple tests are included. |

Please add discussion of motivating use cases. |

This was motivated by the desire to implement chunk-sequence-aware functions in Clojure elegantly. Currently, dealing with ArrayChunks in Clojure is clumsy because few of the functions dealing with collections will work with non-seqables. This functionality will mostly be used by implementers since end users shouldn't care if their sequence is chunked or not. |
