Haskell possesses similar syntax, save that one must prefix an anonymous function with \, like so: \x -> x * 42 It's possible as well to use it bare like that, but only in very particular places, so it's generally much clearer to use it wrapped in parens: (\x -> x * 42) Perhaps some similar convention would make it clearer where a lambda is being used in .js?
