Synchronous setup and teardown for @value decorator.

Value decorator should handle generators.

This is very similar to the contextlib.contextmanager.

class Container(Injector):
    app = App

    @value
    def db_connection(pool):
        connection = pool.aquire()
        yield connection
        connection.release()

with Container as initialized:
    initialized.app.process()

As it turns out contextlib.AsyncExitStack can do all the cleanup job for us. All we need to do is register all context managers in it.

@mastern2k3 thanks for the feedback! It’s very informative! I’m appreciated your effort 👍

I’m totally agree with direction of your thoughts on this 👏

Even added one more thing to teardown logic https://github.com/proofit404/dependencies/issues/549

Problems with order and some parts of error handling could be easily addressed. I’m planning to do it during next week.

Behavior of collecting errors into some kind of group could take more time, and I still want to give myself a chance to think more about this problem before jumping into implementation of the first thing which came to my mind.

I would provide additional details in newly created tickets 🧑‍🏭

Have a good day 🌴 🍸

Cheers, Artem.
