I saw this warning a while ago and I had a recurring reminder to check from time to time to know when it would be safe to use WeightedChoice. It seems master doesn't have this warning so I was wondering if it's fixed.

There is also distributions::WeightedChoice, which can be used to pick elements at random with some probability. But it does not work well at the moment and is going through a redesign.

The "doesn't work well" comment is about the API being difficult to work with; it's not buggy (as far as I know).

0.6 will have a different distribution: WeightedIndex, except that per #601 there might be yet another redesign.

Does that answer your question?
