Using phalcon's DI from singleton?

Question

Let's imagine, that we're developing extremely simple singleton Auth class dealing with DB and session (we don't want any other decomposition like auth adapters etc).

How can I make DI available from this singleton class? Of course, best way is to pass DI instance to constructor, but what if I want it from singleton? Should I use static setter method Auth::setDi($di) or better practices are available? Or maybe we should avoid singletons because we always have DI storage?

I'm sorry for my english, I hope that my question is clear.

You can access the latest DI instantiated statically:

<?php

$di = Phalcon\DI::getDefault();
