If you don't export the methods but do use DefaultSignatures for them in terms of a GHC.Generics version of the class that also works in many cases.

Hi,
for some reason I was under the impression that if I don’t export the methods of a class, then no user of my module can create instances. But I was wrong and in fact they can; the methods will just all be bound to "error ...".
Is there really no way to create a class so that no-one else can create any instances?
Greetings, Joachim
