Thanks for the interest in helping us maintain clear code.
I think actually that the original code was easier than the code with
counter checks. Further more, it moves branches away from loops (easier
optimizable by the JIT compiler). Finally, the new code will be wrong if the
counter overflows/wraps around, which is not unthinkable. 4 Billion elements is
quite within the scope of many applications.
I am curious about other opinions.
