Serialized module

As part of the recent Remote GHCi changes, I moved the module Serialized from the ghc package to ghc-boot. This is because it is shared by the ghci package and ghc itself. The only way to arrange that it was available to both ghc in stage1 and the ghci package (which is not a dependency of the stage1 ghc), was to put it in ghc-boot. Unfortunately this introduces some breakage because some external code import Serialized. I just ran across hint which fails to compile. I can fix this by re-introducing a Serialized module that re-exports module GHC.Serialized. But is that the right thing to do? Serialized is also re-exported by GhcPlugins. Should we be asking people to import that instead? Cheers, Simon
