Stops a mirai if still in progress, causing it to resolve immediately to an 'errorValue' 20 (Operation canceled).
stop_mirai(aio)a 'mirai' object.
Invisible NULL.
Forces the mirai to resolve immediately. Has no effect if the mirai has already resolved.
If cancellation was successful, the value at $data will be an
'errorValue' 20 (Operation canceled). Note that in such a case, the mirai
is aborted and the value not retrieved - but any ongoing evaluation in
the daemon process will continue and is not interrupted.

# Only run examples in interactive R sessions
