It's definitely ignored, and I'd argue that it's a bug in the compiler that
it's even accepted. There's no such thing as a const or immutable class -
just a const or immutable instance of a class. Member functions of a class
can be const or immutable but not the class itself.  Doing so is just
equivalent to marking every function in the class as const or immutable.
Deriving from a const or immutable class is nonsense.
