As to why exactly --i -(-1) runs faster in a while loop than i--, well,
it can't be the same exact pcode or it wouldn't be faster so it must be
less pcode. I didn't bother to verify it myself because at the time,
somebody did for me. It's explained somewhere in the archives. If you

Actually that would be:

If the array is not sorted the best you can do is iterate through all of

It's been proven before here on flashcoders that for in is not faster
than --a -(-1) because it compiles to more lines of pcode. I guess it's
time to use Flasm to bust out some pcode and post it here on the list
instead of making claims based on
