i was thinking of how the stack is used; i would have called what you are
talking about "pointer semantics".  however, on reading around a little,
it seems that i'm in a very small minority (which is a pity, because if
you restrict the meaning to how values are handled on the stack then you
get a lot closer to having just values and references, rather than the
whole pile of different terms that are apparently in use).

sorry for the confusion,
andrew
