~~~~
the syntax `Circle : Shape` means that types that implement `Circle` must also have an implementation for `Shape`.
Multiple supertraits are separated by spaces, `trait Circle : Shape Eq { }`.
Multiple supertraits are separated by `+`, `trait Circle : Shape + Eq { }`.
In an implementation of `Circle` for a given type `T`, methods can refer to `Shape` methods,
since the typechecker checks that any type with an implementation of `Circle` also has an implementation of `Shape`.
