That's exactly what I was after. I knew it was possible, but I was missing "collect" :)
As for symbols, at one point I used them a lot, but then I ran into some places that seemed to really want strings. Out of confusion, I stopped using symbols in a lot of cases. I will re-evaluate where I'm using strings though. Thanks!
