   Stepping back a little, ISTM that there are two major categories of use cases that should be satisfied:
   * applications where the dimensions have well-known names that can map to physical order
   * applications where the dimensions don't have well-known names (they are anonymous) but logical order is a non-trivial permutation of physical order (for example a Numpy array)
   
   Is there a third category of use cases?
