Matthew Heaney and Alexy V Khrabrov have been arguing about the need for
sets. Heaney never uses them and Khrabrov considers them essential.
I've recently used sets for a communications protocol. The task needs to
wait for one of a set of events; at other times it needs to wait for one
of another set of events. The sets of events overlap.
This mapped nicely to a protected object with a current event component.
Each Wait_ entry has a barrier of the form
when Member (Current_Event, Set_Of_Events_For_This_Kind_Of_Wait) is
Another task calls a Signal entry to set Current_Event. This worked very
well.
These are small, simple, discrete sets, as in Pascal, implemented as
arrays of Boolean, as opposed to the set-of-anything components I often
see discussed. I've never needed a set of anything except discrete
values, but I have needed bags of anything.
