[Dune] Returning Geometries As Objects

[Oliver Sander]

This pretty much exactly reflects my view.  I don't think I want the
reference feature in there either.  A variable that looks like an
object but is in fact a reference is a big violation of the principle
of least surprise.  To me, the difficult-to-find bugs that lurk here
are far more serious than potential speed loss.

Concerning the speed loss: are the measurements of how much loss to
expect?  And can that not be mitigated in the calling code by making
sure to call each geometry-Method only once?

best,
Oliver
