Out of interest, why do you need the ::?

[Avi (use Gerrit), 2014/12/22 18:03:02]

Because "get" is used for the name of lots of member functions of the various
base classes of Tuple, and I got the most complicated error messages about how
it couldn't decide which base class's "get" I meant if I didn't qualify it with
the ::.

+  int dpi() const { return ::get<1>(*this); }
+  bool autorotate() const { return ::get<2>(*this); }
 };
