Literal strings in variables are immutable

Similar to numbers, if we declare a variable and assign a string to it as in the following example, that variable is going to be immutable.

fn main() {
    let text = "Hello World!";
    println!("{text}");

    text = "Something else";
    println!("{text}");
}

We get the following compilation error:

error[E0384]: cannot assign twice to immutable variable `text`
 --> src/main.rs:5:5

2 |     let text = "Hello World!";
  |         ----
  |         |
  |         first assignment to `text`
  |         help: consider making this binding mutable: `mut text`
...
5 |     text = "Something else";
  |     ^^^^^^^^^^^^^^^^^^^^^^^ cannot assign twice to immutable variable

error: could not compile `immutable-string` (bin "immutable-string") due to 1 previous error

What happens if we make the variable mutable?
