I don't know everyone's use of \units but for physicists I think that the only 
case where it should be usefull is for 10^something (like \unit{10^-12 second} 
;). Maybe the informaticians need 2^something… The other cases are probably 
marginals.

That's already working and this should be the way when one need something 
unusual. Maybe a support for \m{} should be usefull for those who do not use 
$...$ anymore. For the moment nested curly brackets aren't supported inside a 
\m{} which himself is inside a \unit{}.

All the best.
