Unary unboxed tuple field causes interface file error
Compiling this code under 8.2 or HEAD (but not 8.0), I get an error.
{-# language UnboxedTuples #-}
module Reccy where
data Foo a = Foo (# a #)
Reccy.hs:1:1: error:
Can't find interface-file declaration for variable GHC.Types.$tcUnit#
Probable cause: bug in .hi-boot file, or inconsistent .hi file
Use -ddump-if-trace to get an idea of which file caused the error
