aren't Strings just Arrays? I have looked into the functions of the
class and among them is self[nth] etc.. The same is there for Arrays
Other things are quite common between them. Both support e.g each but
just Array proviced a each_index. I do think that is inconsistent. Of
course I can make String an Array or the reverse but the share so much
in common and IMHO it makes perfect sense to have a each_index for
Strings that I would like to know why that was left out.

I was just wondering, of course I can implement one myself. But anyway
I do not think it makes very much sense if you have the resizable
Arrays. I was just thinking I have overlooked something.
