> The GeoStandardPath object aggregates distances segment by segment using 
> simple addition.  For some kinds of Distance computations, though, addition 
> is not an adequate way to do this.  The xxxSquaredDistance computations, for 
> example, do not produce true squared distances but rather a distance metric 
> that is a combination of both squared and linear.
> I propose adding support in Distance for aggregation, which would allow 
> distance calculators to compute an accurate distance (at some computational 
> cost) instead.
