* [ breaking ] remove parsing of dangling binders It used to be the case that ``` ID : Type -> Type ID a = a test : ID (a : Type) -> a -> a test = \ a, x => x ``` and ``` head : List $ a -> Maybe a head [] = Nothing head (x :: _) = Just x ``` were accepted but these are now rejected because: * `ID (a : Type) -> a -> a` is parsed as `(ID (a : Type)) -> a -> a` * `List $ a -> Maybe a` is parsed as `List (a -> Maybe a)` Similarly if you want to use a lambda / rewrite / let expression as part of the last argument of an application, the use of `$` or parens is now mandatory. This should hopefully allow us to make progress on #1703
