I'd go as far as to say that it's among the most exciting things that has happened to FRP since Conals push and pull paper.\r\n\r\nI was playing with the try-reflex tutorial. I attempted to modify a part of the tutorial program into this:\r\n\r\n```haskell\r\nnx <- numberInput\r\nd <- dropdown \"*\" (constDyn ops) def\r\nny <- numberInput\r\nop <- mapDyn stringToOp $ _dropdown_value d\r\nresult <- op <$> nx <*> ny\r\n```\r\n\r\nBut it turns out that dynamic is not an instance of neither functor nor applicative? Why not? There is both `mapDyn` and `constDyn`?"},"comment":{"url":"https://api.github.com/repos/reflex-frp/reflex/issues/comments/193055529","html_url":"https://github.com/reflex-frp/reflex/issues/28#issuecomment-193055529","issue_url":"https://api.github.com/repos/reflex-frp/reflex/issues/28","id":193055529,"user":{"login":"DiegoNolan","id":1240862,"avatar_url":"https://avatars.githubusercontent.com/u/1240862?v=3","gravatar_id":"","url":"https://api.github.com/users/DiegoNolan","html_url":"https://github.com/DiegoNolan","followers_url":"https://api.github.com/users/DiegoNolan/followers","following_url":"https://api.github.com/users/DiegoNolan/following{/other_user}","gists_url":"https://api.github.com/users/DiegoNolan/gists{/gist_id}","starred_url":"https://api.github.com/users/DiegoNolan/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/DiegoNolan/subscriptions","organizations_url":"https://api.github.com/users/DiegoNolan/orgs","repos_url":"https://api.github.com/users/DiegoNolan/repos","events_url":"https://api.github.com/users/DiegoNolan/events{/privacy}","received_events_url":"https://api.github.com/users/DiegoNolan/received_events","type":"User","site_admin":false},"created_at":"2016-03-07T02:19:11Z","updated_at":"2016-03-07T02:19:11Z","body":"Can you provide some examples of the type of expressions you have in the QuasiQuoter?
