Efficiency vs. simplicity

[Mike Austin]

In passing along event objects down a ui hierarchy, I can either modify the
event and pass it along, or create a new event at each level. The first case
is efficient, but introduces side effects. In the second case, there is a lot
of object creation going on. I was wondering if Ruby uses object recycling
internally? If not I guess I could roll my own, or is it really worth it?

Thanks,
Mike
