Pick a random item from a list of dozen items, where each item has different weight (rarity). If the language permits, the list should be made in a way that makes it easy to add new items to it without having to adjust the weights of the existing items.

Gaming example: random treasure generation in roguelikes. I've found that this is extremely awkward to do in some languages, and simple in others.
