It is easy if you know what to do. But you'll CONSTANTLY run into things where it is obvious that this is a toy that hasn't been thought through. I've found random slowdowns of a factor of 10 for no reason. A context manager needs to have __enter__ and __exit__ methods. An async context manager needs to have __aenter__ and __aexit__ methods. The error you get if you use a context manager as an async context manager or vice versa is big and scary and offers no clue to most programmers of what the problem is. Using async with SQLAlchemy it isn't hard to wind up exiting the event loop before all cleanup has happened. They fixed the main cause of this, but it isn't hard to still trigger it. And so on.
