I know we discussed this on Tuesday's call, but I am really struggling with why I would ever want to do it. It seems to me it is an accident waiting to happen. A type is an abstract reusable thing, I have no idea where it will end up being used, so it is positively dangerous for a discriminator to appear. What is it discriminating? Answer: any surrounding point of uncertainty, no matter where that might be.

Please can someone provide me with a real use case for this?
