tutorial about match can be misunderstood about the role of the "my_number"

[zookoatleastauthoritycom]

Reading http://static.rust-lang.org/doc/master/tutorial.html#pattern-matching, my partner copied the example code:

match my_number {
 0 => { println!("zero") }
  _ => { println!("something else") }
}

into her program, but then was unsure what to do, possibly because she thought that the example code above would define a variable named "my_number". I suggested to her that the tutorial could instead suggest:

fn f(my_number: int) -> void {
    match my_number {
     0 => { println!("zero") }
      _ => { println!("something else") }
    }
}

and that made sense to her.
