"It makes sense for a constant to be a variable"

Reading that made me dizzy. ;) Seriously though thats a bit counter intuitive sounds like "it makes since for 4 to be 2." Not trying to start a debate, just suggesting maybe you find a different phrase, maybe "it makes sense to be able to mark variables as constant", though that still has the same ring to it. Having neither used Readonly or constant I guess I'll be quiet.
