The bounded type parameter `T: Clone` says that `head` is polymorphic
over any type `T`, so long as there is an implementation of the
`Clone` trait for that type.
The bounded type parameter `T: Clone` says that `head`
can be called on an argument of type `&[T]` for any `T`,
so long as there is an implementation of the
`Clone` trait for `T`.
When instantiating a generic function,
we can only instantiate it with types
that implement the correct trait,
