Changed. ReadOnly is now Once.
Furthermore I improved the Elvis operator. You can now write:
Foo f;
Foo f2 = f !is null ?: new Foo();
This will be translated to:
Foo f2 = f !is null ? f : new Foo();
Only the valid identifier will be taken.
But take care of this. If you write int[] arr = other_arr.length
?: [1, 2, 3]; You don't get only 'other_arr', but
'other_arr.length'. This is because of using member
functions/propoerties with elvis operators.
