No, wait, + a whole lot more than that! I've been wanting explicit M2M
join objects for quite some time; this is a pretty neat way to
accomplish it.

Just for shits and giggles, here's another possible syntax I'd been
considering::

    class Role(models.Model):
        role = models.CharField(maxlength=255)

    class Film(models.Model):
        title = models.CharField(maxlength=255)

    class Actor(models.Model):
        name = models.CharField(maxlength=255)
        films = models.ManyToManyField(Film, through=Role,
related_name="actors")

(i.e. Actor relates to File "through" Role.)
