Comment (by Olly Betts):

 From #186:

 > the reason why LatLongMetric has clone() is so that
 LatLongPostingSource::clone() can in turn clone the metric. Optionally
 reference counting the metric would provide the same ability with less
 object copying and better consistency, though this only happens once per
 sub database per query run, so really isn't a hot spot.
 >
 > If we change that, it would make sense to change to passing a pointer
 instead of a reference. The bindings would also need an updating to keep a
 reference to the currently set metric.
