I'd think so. In this day and age it is appalling that we don't quite know how to quickly copy memory around. A long time ago I ran some measurements (http://www.ddj.com/cpp/184403799) and I was quite surprised. My musings were as true then as now. And now we're getting to the second freakin' Space Odyssey!
It turns out that efficiently copying objects only a few bytes long requires a bunch of code. So, I gave up on having the compiler generate intrinsic memcpy code, and instead just call the library function memcpy. This is implemented in the next update.
