[Boost-users] [statechart] Can events carry data?

Is there any provision for "event-local" storage? I'd like to create events that carry data (e.g., timestamp, source, etc.) to be used by reactions and transitions to update state-local storage. I didn't see anything like this in the documentation. Bad idea? Major drawbacks? If it wouldn't be a problem, how might I go about doing it? Regards, Dick Bridges
