So, is there actually a place you plan on not passing true here, or are you just trying to keep existing logic where you haven't explicitly modified it?


(Because i am having a bit of trouble seeing where you would want to pass false.  At the point you are stripping, why is noalias more magical to not strip than anything else that can appear here?)
