do you write a function to do that?
i.e.:
@safe void foo()
{
x = new X();
x.modifyState(5);
immutable(X) ix = ???; // how to write this part
}
If you, the writer of foo(), know that there are no other mutable references to x you can cast it to immutable - but you'll have to mark the function as @trusted.
