The former.  All values stored with dimensionality specified are assumed
to be in the relevant SI unit.

We use the library as a safety check within simulation and modelling of
real world scenarios.  For various reasons, I can't say much more than
that about what we do...  We do use the library to represent *all*
dimensioned variables, and accept the performance hit in compilation
times.  The benefits of checking easily outweigh the downsides.

We've also had to address the absolute versus relative stuff, but that's
a different discussion :-)
