David illustrates it better than I did, but the basic "rule" I tend to
take away is that "__send__" is, effectively, guaranteed to do what I
think it will (I'll see a warning if it doesn't).. whereas "send"
might not. Such concerns aren't that important if you're working on
classes you're familiar with, however, or if methods aren't being
called on dynamically-chosen classes you have little control over.
