That requires one extra variable, and therefore leaves one less register
for the loop itself.

And of course, all these efficiency problems correspond directly to
readability issues. Now that I think of it (I spent almost a year on
this thing, and that part was at the very beginning), I remember that my
reasons for choosing this solution were first readability, and only
second efficiency.
