def access: Task[(A, (Attempt[A]) ⇒ Task[Boolean])]

Obtain a snapshot of the current value of the Ref, and a setter for updating the value.
Obtain a snapshot of the current value of the Ref, and a setter for updating the value. The setter may noop (in which case false is returned) if another concurrent call to access uses its setter first. Once it has noop'd or been used once, a setter never succeeds again.
