that we can convert an `i8` to an `i16` by calling the `into()` method on the that we can convert a variable `x` of type `i8` to an `i16` by calling
`i8`. `i16::from(x)`. Or, simpler, with `x.into()`, because `From<i8> for i16`
implementation automatically create an implementation of `Into<i16> for i8`.
