Inner class constructors should use the argument instead of reading outer `this` from a field because if such an access happens before a delegating constructor call, e.g. when evaluating an argument, a JVM bytecode validation error will be thrown. (The only operation on `this` allowed before a delegating constructor call is SETFIELD, and only if the field in question is declared in the same class.)
