Go does this too. I generally like the idea a lot, as long as it's consistent. The one thing I don't like is the inconsistency. Not sure about C#, but in Go for example ranging strings ranges over runes, but indexing pulls a single byte. And len is the byte length rather than rune length. So basically it's a byte array everywhere except ranging. I guess I would have preferred an explicit cast or conversion to do that instead of by default.
