In the vector example, why not just `collect<...>()` and debug print that, or am I missing the point of what they tried to illustrate?<p>Also, I do agree that C++'s approach to formatting the date was more user friendly/ergonomic, but on the other hand it's not something I've struggled with. I also feel like there is a more succinct version (I don't know if it would have the same performance characteristics and how much that mattered when writing the post).<p>They also later mentioned overall consistency and coherence in the Rust ecosystem, and I value that more over a couple of hand crafted formatters in application code
