+### What it does
+Checks for types that implement `Copy` as well as
+`Iterator`.
+
+### Why is this bad?
+Implicit copies can be confusing when working with
+iterator combinators.
+
+### Example
+```
+#[derive(Copy, Clone)]
+struct Countdown(u8);
+
+impl Iterator for Countdown {
+    // ...
+}
+
+let a: Vec<_> = my_iterator.take(1).collect();
+let b: Vec<_> = my_iterator.collect();
+```
