There is a common pattern in web development of redirecting a user to a login page when their login cookie can not be found. If the login is invalid it regenerates the page with an error message, otherwise it generates the requested page. Could someone show me an example of how to use a functor to generate this functionality for any page?
It's not obvious that there's any particular reason to use a functor here.
I tried this myself and ran into issues like having the Login and HomePage module be mutually dependent on each other. I am not sure what the correct way to do this is.
For mutual recursion across modules, I use URLs built by reference to string paths directly. It forfeits some of the nice static guarantees of Ur/Web, but it's not obvious to me what the right alternate language feature would be.
