Does this code work with PolyKinds
enabled in older versions of safecopy
?
From your report it is not clear if it used it work in older version of safecopy
, and upgrading broke things.
Not surprisingly, this works: instance Typeable (r :: *) => SafeCopy (IntKey r)
, I can't think of a way to do this in the library code off the top of my head. I does seem my version bump was too optimistic.
Hi,
I am upgrading SafeCopy to version 0.10.4.1 and discovered following unpleased behavior. Mostly I concerned with stumbling error message.
The snipped above is just fine until I enable PolyKinds extension. Error message makes impression like GHC is incapable to do the obvious thing!
