The part of this patch that I'm not sure about is dimfunc.  Is that
really necessary?  If I understand the way it works, it seems that it
will be really slow to have nested loops and calling a function
repeatedly instead of working on the full array.  Is there no way to
avoid this using permute/ipermute to rearrange the data before/after
processing?
