#4058: improve error message: Module `System.IO' does not export `LineBuffering'
---------------------------------+------------------------------------------

---------------------------------+------------------------------------------
`LineBuffering` is a constructor, and `System.IO` definitely does export
it. A more helpful error message might be
{{{
`LineBuffering' is a constructor in the data type `BufferMode`,
to import it use
import System.IO (BufferMode(LineBuffering))
or
import System.IO (BufferMode(..))
}}}
