The method expression
(*Api).ListHandler
yields a function with the signature
func(*Api, http.ResponseWriter, *http.Request)
To use the method value with the signature
func(http.ResponseWriter, *http.Request)
you need an instance of `*Api` to call its method, so you can't assign the
handler to the route until after you've initialized the `*Api`.
Don't try to initialize the routes in their top-level declaration, create
the Api, then create the routes.
