Comment (by eschnett):

 Casting away const in C++ is done one a few occasions; const_cast<>() is a
 good way to do so.

 In Cactus, we need to cast away const in thorn CartGrid3D (when setting
 cctk_delta_space) and in thorn time (when setting cctk_delta_time). Both
 are inelegant, and should be replaced by a flesh API instead. However,
 what we currently have works. And since it only involves C, it is safe, as
 Roland explains.
