Yes, according to the docs for GHC 7.8.4 DerivingTraversable
is already supported there. So it's only the FTP breakage problem.
I'm seeing this with one of my packages as well.
Released as psqueues-0.2.2.0
Thanks @erikd and @jaspervdj !
This is an FTP breakage issue. In 0.2.1.0, module Data,OrdPSQ.Internal specifies deriving
Traversable
, butTraversable
is not in scope. Also, does theDerivingTraversable
extension even exist in GHC 7.8.*?
