Yay, I finally got the singleton working with allocation and lifetime policies, in addition to being in CRTP form. I know that threading policies still remain, however I would like an opinion on what I have so far. A major difference from Loki is that my lifetime policy needs to know about the allocation policy in order for dependencies to be possible to implement. The code is available here: http://www.ezequal.com/chaos/libs/policy_singleton.h After I am assured that the structure of the code is pretty much correct, i will begin adding additional policies, such as the longevity lifetime that Loki supports. If there are policies that Loki doesn't provide that might be widely useful, please mention them so that they can be incorporated. I look forward to any and all feedback. -Jason
