   I mean, one way or another the out of bound communication has to happen. In 
the cases of names, the out of band communication is "sender and receiver agree 
on common meaning of particular string names" and works pretty OK for specific 
domains (e.g., images) where these conventions agree. With the case of a layout 
permutation, the communication is "sender and receiver agree on the semantics 
of the positions of logical dimensions (e.g., after you apply the 
permutation)." This is more general because you don't have to have agreed on 
names for a particular dimension. The user code can then do whatever it needs 
(e.g., pass `channels_last=True/False` to an operator on the image) to line up 
the logical interpretation.
