 In our example, `0..10` is an expression that takes a start and an end position,
 and gives an iterator over those values. The upper bound is exclusive, though,
 so our loop will print `0` through `9`, not `10`.

+Rust does not have the “C-style” `for` loop on purpose. Manually controlling
 each element of the loop is complicated and error prone, even for experienced C
 developers.
