#2668: Standalone deriving doesn't do newtype deriving properly

Comment (by ryani):
Oops, that was just a typo in my test case.
Change the instance to declare ret as
{{{
ret :: a -> m i i a
}}}
It compiles fine with the standalone commented out in GHC6.8.3 but gives
the same error with it in.
I'll upload a fixed attachment.
