* The value passed some validation when it was created, so you no longer have to validate it again at every use: 'PhoneNumber(String)` or `OddNumber(u32)`.
* Demonstrate how to add a `f64` value to a `Newtons` type by accessing the single field in the newtype.
* Rust generally doesn’t like inexplicit things, like automatic unwrapping or for instance using booleans as integers.
* Operator overloading is discussed on Day 3 (generics).
