Acquire a resource within a Pull.
Acquire a resource within a Pull. The cleanup action will be run at the end
of the .close scope which executes the returned Pull. The acquired
resource is returned as the result value of the pull.
Like acquire but the result value is a tuple consisting of a cancellation pull and the acquired resource.
Like acquire but the result value is a tuple consisting of a cancellation pull and the acquired resource. Running the cancellation pull frees the resource. This allows the acquired resource to be released earlier than at the end of the containing pull scope.
