And as Romain pointed out before the template programming means that we're
saving temporary objects.  So it can be cleaner to read and be more
efficient, now that compilers have caught up.

Ha :)  Talk to Andrew Runnalls about how his CXXR reimplementation is coming
along.  He has a new object structure in there but alas no sign of Armadillo.
