### What it does
Checks for usage of `_.cloned().<func>()` where call to `.cloned()` can be postponed.
### Why is this bad?
It's often inefficient to clone all elements of an iterator, when eventually, only some
of them will be consumed.
### Known Problems
This `lint` removes the side of effect of cloning items in the iterator.
A code that relies on that side-effect could fail.
### Examples
```
vec.iter().cloned().take(10);
vec.iter().cloned().last();
```
Use instead:
```
vec.iter().take(10).cloned();
vec.iter().last().cloned();
```
