+-- GHC 5.00 doesn't handle this:

+--  Could not deduce `?wibble :: t' from the context ()
+--  Probable fix:
+--      Add `?wibble :: t' to the banding(s) for {y}
+--  Or add an instance declaration for `?wibble :: t'
+--  arising from use of implicit parameter `?wibble' at tc122.hs:18
+--  in the definition of function `y': wibble
