This is odd...Why is "c" at position 1 and "d" at position 2?
This is only possible if the string-index does not start at 0
(as lists do start at 0, this is confusing..)
but thats not the case ->

It is confusing when the length to push is bigger then the string itself, then we
have to deal with an exeption.. a round-robbin counter in this case...
