This kind of thing can still be necessary.
I like using recursive functions, whenever possible. It seems quite elegant to me, but I have learned that said elegance comes at a price.
For example, if you need to search and replace a given character in a string of characters (for export to csv reasons, for example), if you have to write your own s&r function for whatever reason, you'd better be sure that the original string isn't too long and that there aren't too many occurences.
Otherwise, your code will crash with a memory overflow error due to the amount of instances of the recursive function.
In that case, there's no choice but to deal with a loop function and handle everything in one instance.
It's a bummer, but it works.
