Haskell '98 apparently features 25 reserved words. (Not counting "forall" and "mdo" and so on, which AFAIK are not in Haskell '98.)
21 actually. case, class, data, default, deriving, do, else, if, import, in, infix, infixl, infixr, instance, let, module, newtype, of, then, type, where. There's also three special words that can still be used as identifiers, so aren't reserved: as, qualified, hiding.
Okay, 'as' is easy. But can you find a situation where 'qualified' or 'hiding' would be natural choices for an identifier? I'd love to see those in some code :)
