Okay... I could not find something that was exactly as my Kata and there is a myriad of fundamentals/string Katas, so how novel should one be is my question? Anyhow... I'll take your point in that I should read through the documentation more thoroughly.

Clever because readable, I think ^^.

What an elegant solution!
