"""
Sometimes in your Django model you want to raise a ``ValidationError`` in the ``save`` method, for
some reason.
This exception is not managed by Django Rest Framework because it occurs after its validation 
process. So at the end, you'll have a 500.
Correcting this is as simple as overriding the exception handler, by converting the Django
``ValidationError`` to a DRF one.

def enable_timeit(number=1000, repeat=1):
    """
    Adds a `timeit` member function to the decorated function.

    This function allows for configuration of how `timeit` will be executed for
    the decorated function. Note that ultimately, `timeit.repeat()` will be
    called, not `timeit.timeit()`.

    Args:
        number (int): How often `timeit` should execute the function.
