Comment (by simonpj):

 Spot on.  GHC's front end makes no particular effort to maintain the
 original declarations in the order they were given.  While it was just a
 front end for the compiler that was fine, but now it's being used for
 Haddock and other back ends I can see that being more careful about this
 would be good.

 I'd be happy to accept a patch.  (It's not hard, as you observe.)

 There may be other places in the parser where this kind of things happens,
 I'm not sure.

 Simon
