That's funny. I've only reviewed and debugged these things, but I don't
think I've actually written any code that would have used these macros!
As someone trying to debug and review, I love how this looks.
It gets the point across much more clearly about what is going on to me
as a reviewer and I appreciate that. memcpy()s contain a lot of gunk
that my brain can't parse easily, but this is rather clean, and it
*HALVES* the number of lines of code I have to look at.

That's exactly my point. We're not trying to save development time here
at all. My argument is that this reduces the maintenance and review
