RE: garbled error message

Thanks for the report.  I'm not 100% certain why it happens in 5.04.2,
but  it doesn't happen in the HEAD.  The error message is still not
great, but at least it's not gibberish.

Data.hs:288:
    Could not deduce (ReprType r t) from the context ()
      arising from use of `getter'' at Data.hs:288
    Probable fix:
        Add (ReprType r t) to the expected type of an expression
    In the first argument of `runDR', namely `(getter' repr)'
    When checking the type signature of the expression:
          runDR (getter' repr) "..." 0 rContents :: forall t. CC t
    In a 'do' expression:
        val <- runDR (getter' repr) "..." 0 rContents :: forall t. CC t
