Conclusion
So, we have taken a single utility method and gone through and cleaned it up and then extended it to be more generic and useful.
In the process, we transformed the relatively slow and problematic use of tail recursion as an implicit looping construct
into the faster, safer, and clearer use of the while explicit looping construct. We have also seen how minor changes to the routine made point of the code more explicit and clear.
