This might not be useful more generally, but that `if`-`let`-`else` could be shortened to `print!("{}", v.unwrap_or(&", "))`.

Edited to add: The `for` loop could be

```rust
for v in elements.iter().intersperse(&", ") {
    print!("{v}")
}

```

That seems too simple, so I guess it likely isn't useful.
