I was thinking about this as well as these streaming things become more popular. Would you write add-to-cart events and those trigger add-cart events; the latter containing an valid field which will become false after the 10th add-cart. So after that you remove-from-cart which triggers add-cart which then becomes valid again < 11 items? And transactions similarly roll back by running the inverse of what happened after the transaction started. I'm just thinking out loud. I understand you probably wouldn't use this for that, but let's have some fun shall we?
