One element tuple

---

• We can create a one-element tuple by putting a comma after the element, but probably there is not much value in it.
• It is better to just create a variable holding that single value.

fn main() {
    let thing = ("text",);
    println!("{:?}", thing);
    println!("{}", thing.0);

    let thing = "text";
    println!("{}", thing);
}

("text",)
text
text
