------------------------------------------------------------------------ --------------------------- data AParser String = AP {apapply::([String]->[(String,[String])])} Whoa! You can't declare a data type like that! You must have a type variable after the data type name, thus: data AParser a = AP .... It's an egregious bug that GHC does not reject your data type declaration. After that, all bets are off. Some deeply-wired-in invariant is not being obeyed, and all manner of bad things may happen. Thank you for showing up the bug -- I'll fix it. Simon
