> Why optimize your syntax with `len(txt)` and `txt[0]` when, as you point out, you can't do that? I like Rust's approach. It's a strings-are-UTF8 language but strings (both str and String): - are not directly indexable - force you to be explicit when iterating: you iterate over either `s.chars()` or `s.bytes()` - are called out in the docs as being a vector of unsigned 8-bit integers internally - support a len() method that is called out as returning the length of that vector - can be sliced if you reaaaally need to get around inability to index directly but attempting to slice in the middle of a character causes a panic
