+### What it does
+Checks for usage of `inspect().for_each()`.
+
+### Why is this bad?
+It is the same as performing the computation
+inside `inspect` at the beginning of the closure in `for_each`.
+
+### Example
+```
+[1,2,3,4,5].iter()
+.inspect(|&x| println!("inspect the number: {}", x))
+.for_each(|&x| {
+ assert!(x >= 0);
+});
+```
+Can be written as
+```
+[1,2,3,4,5].iter()
+.for_each(|&x| {
+ println!("inspect the number: {}", x);
+ assert!(x >= 0);
+});
