The problem with this kind of discussion is that the semantics of the rest
of the language effect the discussion so much. Specifically a language may
have semantics such that the programmer can only use call by value, but
the implementation can implement everything using call by reference (a
language like Sisal comes to mind here). Whether one calling convention is
better than the other becomes pretty moot in this kind of set up.
