When should one use references rather than passing by value to
overloaded operators?

I realise that references will save some overhead for large structures,
but the rather scanty manual I have, seemed to indicate that there is
another reason. It (the manual) also hinted at situations when it would
be preferable to pass one of the parameters by value and the other by
reference. Can anyone help?
