-// **Exercise 03.1**: Define a trait `Print` to write a generic version of

+// **Exercise 03.1**: The goal is to write a generic version of `SomethingOrNothing::print`.
+// To this end, define a trait `Print` that provides (simple) generic printing, and implement

 // I will again provide a skeleton for this solution. It also shows how to attach bounds to generic
 // implementations (just compare it to the `impl` block from the previous exercise).
 // You can read this as "For all types `T` satisfying the `Print` trait, I provide an implementation
