Comment (by anonymous):

 This would be really nice to have this. Without it, you can't specify
 array sizes based on math done with "units". ex, I can't do this:

 constexpr quantity<time> secs_4 = 4*seconds;
 constexpr quantity<time> secs_2 = 2*seconds;
 constexpr int array_size  = static_cast<int>(secs_4/secs_2);
 int an_array[array_size];

 I also converting everything to "static const" instead of constexpr, but
 that didn't work either.
