The history of this sub is probably I wrote a once off script, that is now gone. I liked the sub so plonked it my my Util::Sort with all my other sorting subs. It is easy enough to figure out how to use, so no usage was written for it anywhere. It has been sitting in my Util::Sort module a long time growing metaphorical moss.

I have not written any tests for any of my work yet. I am writing all the POD first, then I will get to the tests, eventually. The last time I looked at the Test suite of modules, I got so confused on their usage, that I just quit trying. That was years ago when I was still learning how to write and had severe confidence issues. I still have confidence issues, though not as severe.

It will be especially hard to write tests for the modules I wrote and do not use.
