> It does create a new list, but aliases the scalars rather than copy them.

Right, but I thought that using each didn't create a new list. But slapping a quick Benchmark together I see that keys is nearly 3x faster than each, and values is more than twice as fast as keys ... that totally blows my understanding of the process. And here I've been favoring each over keys or values on the grounds that it used less memory and was faster ... man have I been wrong!
