This is an important part of the range design. This range is useful for other things too, like:
- increasing efficiency of some lazy operations, as already done in Clojure. A buffer is meant to be CPU cache friendly, increasing performance of numeric code too.
- Buffered I/O
- The chunked lazy parallel map dsimcha is working on
- Creating a chunked interface in Phobos for DBMSs
