Potential feature: get #9
Description
In Swift, Task has an overloaded get that is throwing iff Failure is Never.
In the same way, we should probably combine .asyncThrows and .async and .value and .result into a single overloaded function called .get the result would be async and/or throwing depending on the underlying implementation. Then if the async/throwing status of a chain changes, you don't have to change the name of the thing that accesses (one fewer thing to change).
