 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.

-# Enumerate
-
-When you need to keep track of how many times you already looped, you can use the `.enumerate()` function.
-
-## On ranges:
-
-```rust
-for (i,j) in (5..10).enumerate() {

-i = 2 and j = 7
-i = 3 and j = 8
-i = 4 and j = 9
