SPJ writes in #GHC9079:

Well, this looks to me like a bug in the Haskell 2010 report

  • Section 8.4.2 says that newtypes must have their constructors visible, and claims that Foreign.C.Types follows this convention.
  • But Chapter 28 which shows Foreign.C.Types manifestly does not follow this convention.

That looks like an outright contradiction.

I think we should export all the data constructors in Foreign.C.Types in the haskell2010 package. Does anyone disagree?
