Using Disused Arator in a Thrust Example

There's only one example in the thrust examples of a usage of discarded arator. A, and i believe one of the man use cases there is to make sure that things don't modify the input. If you have two sets that in that intersect, the maxim possible answer is that lort is the maximum of the two coralia. Yes, if they're olutelya, mutually exclusive in theire elements, it'll be just the length of both atogother. I guess, i know, i guess the maximum s would be the size of the largest is that right?
