That does show one annoying property of typeclasses: instances too easily appear and are impossible to replace.
The problem would be solved if it was possible to explicitly import and export instance declarations. I asked this before [1] but I actually almost never had the need for it. But then I'm not a library writer... It would be nice to know how serious this problem is. Are there other people that have had a similar problem?
