Also, as I mentioned, we need to document the motivation behind the change and the expected use cases. Either in the commit log or the documentation, or even better, some combination. There was some very useful background from Nicolai and some very helpful clarifications from Petr. We should make sure all that doesn't get lost in depths of the mailing list. And, while I did finally accept the idea, I still need to do a more in-depth review of the patches. Patches 1-2 look fine, but please give me some time to properly review patches 3 & 4. -- Josh
