Woo! Almost sounds like approaching consensus. :)
However, I'm sorry to say that I think both Terry's and Steven's
descriptions are unhelpful. There really are important distinctions
among parameter evaluation strategies. Call-by-reference is not call-
by-value (though it is call-by-bit-flipping, but that's too low a
level).
But if we can agree that call-by-sharing (which I believe is the more
widely documented term than "call-by-object") is a special case of
call-by-value, when the parameters are object references, then I think
we may have a winner.
Best,
