In answering a forum post I noiced that I wanted this and it was missing. Also, extensive comments Also, rename the length: init parameter to count:. When writing the comments for the init function it became painfully clear why we use "count" is better than "length" especially around pointers and memory: the former is much less easy to mistake for "length in bytes". Plus it's consistent with the new ".count" property Swift SVN r20609
