In many ways, a string is more useful to treat as a scalar than a collection, so drilling down into collections and ending up iterating individual characters as the leaves is often 1 step too far.
I think the key word here should be "sometimes". A lot of the time I do treat strings as scalars (or more often, string.split() as a sequence of scalars), but sometimes a string absolutely is a sequence of characters, and I want to be able to treat it as such.
I have to admit that most of the time that I end up in trouble because of unexpectedly iterating through a string, it's my own stupid fault. Almost always I have been doing something over simplistic or wrong-headed, usually returning a string from a function when I meant to return a list of (one) string(s) instead.
