 The `for` keyword can be used as sugar for iterating through any iterator:

 implementing the `FromIterator` trait. For example, the implementation for
 vectors is as follows:

 The `Iterator` trait provides a `size_hint` default method, returning a lower
 bound and optionally on upper bound on the length of the iterator:
