I noticed this while going through the SOE book:
$ hugs ERROR "/lusr/lib/hugs/lib/exts/ST.hs":49 - Syntax error in type expression (unexpected `.')=20
This is due to the fact that ST.hs uses forall types, which are not part = of=20 Haskell 98. The error reflects is due to the "." in "(forall s . ST s a)= =20 -> a" because that's not part of Haskell 98 type syntax.
Run hugs with -98 to use this and many other extensions, and you should b= e=20 fine.
