I strongly favor creating instances like this.
Not having them just makes the world more painful to debug code to make a normative point and leads to greater code fragmentation when someone else has another stance.
I agree. Being able to look at some value "the dirty way" is an important use case of Show (be it as a return value or via trace), and I see no reason for any datatype to not support Show when it could. On Read I don't have an opinion because I usually try to avoid it :-) +1 David/quchen
