I think it makes sense to keep Task Locals for as long as curio supports Python < 3.7
Since 3.7, one could use PEP 550 task locals.
Locals have been deprecated and moved to an example. Should anyone need the code they should copy it from there and use it.
In light of discussion surrounding PEP 550, I'm thinking about deprecating task locals as a core feature of Curio. For one, the whole concept seems fraught with subtle peril. Second, there are a variety of different ways that one might achieve the same effect (e.g., passing around context explicitly). As such, it's not clear that Curio needs to necessarily enforce a "there's one way to do it" rule on it. Lastly, the current locals implementation is something that could just as well be moved to a third-party library if you still wanted it (as it's fairly modular). Plus, I generally like the idea of keeping Curio small.
