This last point is not obvious at all, in my opinion. Why not? In principle, certainly const-ness *can* help optimizers one way or the other. Is this just a current limitation? A design choice? Anything in the standard making that tricky? I would like to know more. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25845
