Camm, thanks for taking the time to write about this stuff. I'm more broadly interested in all of it, but in the interest of brevity I'll just make a quick note.
It sounds like part of the proposal is to let program behavior change with the compiler optimization setting. I'm pretty uncomfortable with that -- it would make it pretty hard to predict what some code is going to do. There's no guarantee that the optimization flag is the same one time as another, so one can't know whether the program will behave the same. I'll let that be enough for now and try to address some of the other stuff later. best Robert
