Compare with Rust where you can't "reverse" a string - that is not a defined operation. But you can either break it into a sequence of characters or graphemes and then reverse that, with expected results: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=6335bb2c5cacf308ed5190deaba0121f https://play.rust-lang.org/?version=stable&mode=debug&editio... (Sadly the grapheme segmentation is not part of standard library, at least yet)
