Hi all, For example, if I write in a do block: x <- action1 y <- action2 z <- action3 return (f x y z) that doesn't require any of the context-sensitivty that Monads give you, and could be processed a lot more efficiently by a clever Applicative instance (a parser, for instance).
What advantage is there in using Applicative rather than Monad for this? Does it _really_ lead to an efficiency increase? -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
