Build failure with GHC 8.2.1 as seen on the Stackage build server.

[1 of 6] Compiling Transient.Internals ( src/Transient/Internals.hs, dist/build/Transient/Internals.o )

src/Transient/Internals.hs:96:26: error:
    Not in scope: type constructor or class ‘TypeRep’

Do you know the version of the package base used?

DanBurton commented

The one that ships with GHC 8.2.1: base-4.10.0.0

agocorona commented

need to import Data.Typeable.

However there are some other dependencies that still does not compile with ghc-8.2.1. IIn particular, atomic-primops, which is a new dependency. will take some time before this packages is actualized.

rrnewton/haskell-lockfree#66

As soon as it is available I will create a new version.
