Very cool, I've got a couple of question: the readme references optimized
transfers, what qualifies as an optimized transfer? Also, would it be
possible for byte-streams to give an estimation of the number of memory
copies that happen in a given conversion (maybe this is as simple as the
number of steps...)? Thanks for releasing this!
