Yes, this is generally true. All modules should get loaded
before \starttext.

Well, I had never tested them together, and given the very
extensive changes nath enacts, I'm not surprised it doesn't
work.
Anyway, it looks like the fix is easy: the problem is that
dimension commands are not protected (unexpandable).
In m-units.tex, look for the lines
\def\dimensionprefix#1%
{\gdef\thedimensionprefix{#1}}
\def\dimensionaddfix#1%
{\unskip
%\mathematics{\umathematicstypeface#1}%
\ustartmathmode\umathematicstypeface#1\ustopmathmode
\nobreak
\hskip\dimensionaddfixsignal}
\def\dimensionnopfix#1%
{\dontbreakdimension
\ifdim\scratchdimen=\dimensionpowersignal\relax
\ustartmathmode
\else
\ustartmathmode
\udimensionhalfspace
\nobreak
\fi
\umathematicstypeface#1%
\ustopmathmode
\nobreak
\hskip\dimensionsignal}
\def\dimensionmidfix#1%
{\dontbreakdimension
\ifdim\scratchdimen=\dimensionpowersignal\relax
\ustartmathmode
\udimensionbackspace
\nobreak
\else
\ustartmathmode
\fi
\umathematicstypeface#1%
\ustopmathmode
\nobreak
\hskip\dimensionmidfixsignal}
\def\dimensionpower#1%
{\gdef\thedimensionpower{#1}}
and change each
\def\dimension...
into
\unexpanded\def\dimension....
This should solve the problem.
I'm not 100% sure this is the best solution, though. An
alternative could be to keep those definition as they are and
instead make unexpandable the actual commands (\Micro etc).
Hans, what do you think?
