           Summary: Writefln on null object should not trigger access error.
           Product: D
           Version: 0.173
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: wbaxter at gmail.com


Class o = null;
    writefln(o);

This should just print out 'null' (or maybe "(Class)null" if that info is
available) rather than triggering an access violation.
