/*
Because it's promise-based
It's not like Express which is callback-based
next() simply returns a promise that is resolved when the next chain of middleware is done,
which is what allows a single Koa middleware to act as a before and after
If you are using await next() then you dont have to return is,
because the middleware calling await isn't done until it reaches it's end

I should probably do a small tutorial on how Koa middleware works some day


https://eev.ee/blog/2013/03/03/the-controller-pattern-is-awful-and-other-oo-heresy/


is it simply doing app.clients = [] ? not sure if antipattern, polluting the app namespace like that


catch(NetworkFailure failure) {
    // Retry the request now or later
    ...
}
