Takes any number of iterable objects or objects with a length property and returns the longest one. 
If multiple objects have the same length, the first one will be returned.

Use `max()` with `len` as the `key` to return the item with the greatest length.

```py
def longest_item(*args):
  return max(args, key=len)
```

```py
longest_item('this', 'is', 'a', 'testcase') # 'testcase'
longest_item([1, 2, 3], [1, 2], [1, 2, 3, 4, 5]) # [1, 2, 3, 4, 5]
longest_item([1, 2, 3], 'foobar') # 'foobar'
```
