Comment(by Rhys Ulerich <rhys.ulerich@…>):

 I'd failed to notice that boost::multi_array_ref maintains its stride
 information in a protected member named stride_list_.  I have achieved
 what I was after by subclassing and modifying stride_list_ directly.

 From what I can read in the code, mutating stride_list_ underneath
 multi_array_ref should have no ill side effects.  If it does, what are
 they?  If not, would you please add a constructor to multi_array_ref that
 supports arbitrary strides by invoking the super_type's constructor and
 then modifying the stride list directly?
