Comment(by Feuerbach):

 Sorry, I wasn't clear. I am puzzled by the fact that in a bare ghci
 session, without importing any additional modules except Prelude,

 1) The type `IO` is available under the name `GHC.IO.IO`
 2) The data constructor `GHC.IO.IO` is in scope

 In ordinary Haskell, you'd need to `import GHC.IO` for that to be the
 case. Hence my question.
