Yes, but unlike what every redditer is say, that doesn't mean the 
compiler can do whatever it wants. It means you can't define its 
behavior. Go ahead try.

Throws an exception, nope, can't do that no information at run-time and 
const is already gone from a cast during compile-time.
Modifies value, nope, might not be possible.
Does nothing, nope, same as throwing exception.
