I find the clarity of this example important because the implementation of (ring/get-match) c23f591283/modules/reitit-ring/src/reitit/ring.cljc (L309) doesn't explain what's going on here.
I find the destructing of the qualified keyword `::roles` unnecessary to the example. To this end I propose using an unqualified keyword.
Additionally there is a collision between the name of the required rolls to access the route and the name of the roles held by the user making the request. To this end I propose having the roles held by the user named `:my-roles`
It's possible to put the :keys keyword in the namespace of the keys one likes to
destructure. With that one can use symbols in the vector again. One advantage of
having symbols is, that Cursive grays them out if not used. I found two
occurrences of unused destructured keys.
