a) I am also against supporting references; and said this much, much earlier,
   - have a look at the last paragraph of http://www.eda.org/sv-cc/hm/0820.html
b) Until now nobody demanded supporting of references by DPI
c) My feeling was that we reached agreement during the last call about default values and support of call by name

This is just asking Swapahnajit and Ghassan whether we could have a poll on this issues, since I think we can easily close them or did I
miss something ???
