The issue is that what one wants is what our strings do: indexing by code units and getting characters. My inclination is that there should be `codeunits(str)`, `chars(str)` and `graphemes(str)` and they should all be indexed by code unit, but maybe wrapped in a `StringIndex` type that you either can’t just do bare arithmetic with or that remembers the string the index is into and does the right advancing when you do arithmetic with it.
