Comment (by simonpj):

 Note: current unboxed tuples are eta-expanded by `CorePrep` since
 `Id.hasNoBinding` returns True.  So we don't need to worry about
 generating curried versions of them.  Nor would be possible to do so,
 since unboxed tuples can have unboxed components of varying width; they
 are not parametrically polymorphic.

 See also `Note [Primop wrappers]` in `Id.lhs`.
