I'm totally new to the const/immutable thing, so this might be a naive

The spec says:
"modification after casting away const" => "undefined behavior"
I thought it was "you're on your own", not undefined behavior. The
former implies there is some "right" way to do this if you know more
about the data than the compiler, the latter implies that there is no
right way to cast away const. Am I wrong?

I think you're wrong. It's OK to cast away const, as long as you don't
modify the thing which is supposed to be const.
But if you modify it, there's no way the compiler can guarantee that
your code will work. Anything could happen.
