In any case, I'm assuring you: getting the results "out of tasks" is trivially easy.

I don't get this. Can you please explain more what you have in mind and I'll try to help clarify things.
What I mean is I assume any real program is not going to be creating and destroying event loops any time they want to do something Async and that they'll essentially run main in a top level Async do. In fact it seems like that's the only safe thing to do with this library because the following snippet changes semantics depending on whether it's nested in an existing event loop or not.
results = []
Async do
sleep 10
results << "Hello"
end
puts results
Sync do
results = []
Async do
sleep 10
results << "Hello"
end
puts results
end
