it's been a while since I've used POE, but lately I've been reminded of this bit from it's documentation, which I think about constantly for some reason
POE is event driven. Wait. What does that mean? To draw a somewhat relevant analogy... For most geeks, life is event driven. Most of the day is spent waiting for something interesting to happen.
Ponder a friday evening. We're talking about a geek here so not much is going on. Just bad american tv. (is there any other kind of american tv?) Delivery Pizza arrives. This causes the geek to scramble for cash, pay the delivery man, and then hungrily devour pizza. When the pizza is gone, the geek resumes watching tv.
The arrival of the pizza is an event. This causes a Pizza Arrival state, the collection of actions including paying for the pizza and eating it. When the Pizza Arrival state ends, the geek goes back to a passive wait state, waiting for the next event in his/her life.
