null references & dereferencing null pointers


1) That null references explicitly be defined as legal in the language.  A 
null reference is that which is created from a "dereferenced" null pointer
such as follows:

	FOO& fooref = *((FOO*)0);

2) That "dereferencing" null pointers except in the initialization of references
be explicitly defined as not legal in the language.  The exact effect
of dereferencing a null pointer would be "implementation defined", but the
intent is that no legal object can be referenced via a null pointer.
