Defining null references has been on the table too. I wrote a paragraph 
about them and then deleted it in fear of major aggravation.

There's no need for new syntax. We can easily define things such that 
you can return *null when a reference is expected and checking 
&(r.popNext()) is null to figure out what's happening. I think it's bad 
design though.
