With the new UNPACK pragma warning, this statement is obsolete:

"If a field cannot be unpacked, you will not get a warning, so it might be an idea to check the generated code with -ddump-simpl."

(I couldn't find the docs for a newer GHC version, if they have been fixed since please ignore this bug.)
