However, this might not be an issue, as I believe all the constructors of all or almost all types in time are public. If it is possible for a user of time to hand-write instances of Data using only what time exposes, then it is safe to include those instances in the package.
I recall trying this some time ago. I think I gave up when I decided that I also needed Data instances for Data.Fixed. I was probably doing it wrong, but it was too large a yak for me to shave. Alistair
