Re: [Haskell-cafe] Applicative but not Monad

Formlets are not Monads. http://www.haskell.org/haskellwiki/Formlets If you tried, you could actually implement a Monad instance for Formlets, but it would lead to very undesirable behavior. Specially, if a field in the form failed to validate, then the rest of the form would not be rendered at all. - jeremy On Oct 30, 2009, at 11:14 AM, Yusaku Hashimoto wrote:

Hello cafe, Do you know any data-type which is Applicative but not Monad?
