That would speed up my tinkering, certainly.

I did have a d'oh moment: you can write

   data Foo = Moo {goo :: Int}  -- braces where a type goes

and indeed, commenting out field declarations makes happy
happy. However, these { exp } guys never stand as types of
things, only as parameters of types, so it might be possible
to resolve the problem without fat brackets. Whether it's
worth it is another matter...
