               while (defined($_ = $d->read)) { something_else($_); }
               undef $d;

       The only objective benefit to using "DirHandle" is that it avoids
       namespace pollution by creating globs to hold directory handles.

           with a ':'.  If specifying a volume name only, a trailing ':' is
