    """Iterator slicing works just like sequence slicing, including support for negative indices and slices, and support for `slice` objects in the same way as can be done with normal slicing.

    Coconut's iterator slicing is very similar to Python's `itertools.islice`, but unlike `itertools.islice`, Coconut's iterator slicing supports negative indices, and will preferentially call an object's `__iter_getitem__` (Coconut-specific magic method, preferred) or `__getitem__` (general Python magic method), if they exist. Coconut's iterator slicing is also optimized to work well with all of Coconut's built-in objects, only computing the elements of each that are actually necessary to extract the desired slice.
