GHC.Unit (like all GHC.* modules) is an internal module used by GHC to
implement base, containers, etc.  The actual definitions of tuples in
the Prelude "come" from Data.Unit, which for GHC are just re-exported
from GHC.Unit: http://haskell.org/ghc/docs/latest/html/libraries/base/src/Data-Tuple.html
