A nice. I jumped into 4.3 and found

So it must be 'atype' instead of 'tyvar'? Haskell 98 is really mighty.
Oh. Don't I look silly? You were absolutely right, it's not Haskell 98.
Me too. I've looked at the type declaration syntax instead of instance
declaration one.
Maybe the report is not complete? I mean, the current behaviour of Hugs
and GHC (as I observed it) is more consistent, and maybe that's what the
designers had in mind.
Actually Hugs does reject it without flags. Maybe you have a -98 stored
somewhere?
When starting, my Hugs tells
Haskell 98 mode: Restart with command line option -98 to enable extensions
