It's a nice Quality of Life addition, that I would like to see with C++ as well.
I wish they don't implement f-strings and s-strings, at least for now. Even if they are more ergonomic than the `format!` and `String::from`, they hide a memory allocation which is not really indicated in a language like Rust and would be really weird in a context without an allocator. The only solution to this would be `const` evaluation of this, but that would restrict their use to `const` environments, so mostly unusable.
