I think requiring this_ is fine.  I was a bit worried about the
possibility of silent failure when people forget (quite likely to happen
during refactoring) but luckily there are very few circumstances I can
thing of where it wouldn't give a compile error when you accidentally
use this (the two that spring to mind are printing out the value, and
reinterpret_casting it).  Still, if there were a way to make it
impossible to use 'this' at all, that would be nice to avoid this risk
(but I doubt you can).
