I'm not quite following this. You mean, that you can replace 'view' with
the term 'implicit def' throughout the literature without compromising
accuracy?

What do you mean by 'what if the view is the identity'? Do you mean the
identity natural transformation? (forall x. id x = x). If so, I still
don't see your point.
