I like it. I could imagine a setup like this:

class YesodPermissions master where
    data Permission master
    hasPermissionTo :: ...

isAuthorizedPermissions :: YesodPermissions master => Route master ->
Bool -> GHandler sub master AuthorizationResult

It could sit next to YesodBreadcrumbs in Yesod.Core as a "you don't
*have* to use it, but it's really convenient to do so."
