That's fine. But then you can choose
a) add -fno-warn-orphans
or
b) move the (Show Day) instance to the module declaring Day.
I'm not sure which is best for you, but you're the package author so you get to
decide!
Patch pushed. I've plumped for option a. It's better structuring, as b
would involve moving more code from Gregorian.hs to Days.hs.
The concern Henning raised shouldn't apply, as both modules are hidden
and re-exported by Data.Time.Calendar. I've also fixed two other modules
with the same issue (again, also hidden).
