Like in case of summation on a list you start with the result seeded
to 0. In case of multiplication (factorial) you start with the result
seeded to 1. In case of ORing a list, we start with the result seeded
to false. And in case of ANding a list, we start with the result
seeded to true.

Similarly is we think about sc_event_and_list, we would seed the
result with an immediate event. And for sc_event_or_list, we should
seed the result with an event that never gets notified.
