-### What it does
-Checks for looping over the range of `0..len` of some
-collection just to get the values by index.
-
-### Why is this bad?
-Just iterating the collection itself makes the intent
-more clear and is probably faster.
-
-### Example
-```
-let vec = vec!['a', 'b', 'c'];
-for i in 0..vec.len() {
-    println!("{}", vec[i]);
-}
-```
-
-Use instead:
-```
-let vec = vec!['a', 'b', 'c'];
-for i in vec {
-    println!("{}", i);
-}
-```
