            builder.dupeWide().loadThis().dupe(2).pop();
        } else {
            builder.dupe().loadThis().swap();

        // At which point the stack is the result value, this, the result value
        builder.putField(plasticClass.className, node.name, typeName);
    // And now it is just the result value
    }
    builder.returnResult();
    plasticClass.addMethod(getAccess);
    plasticClass.redirectFieldRead(node.name, isPrivate(), getAccess);
}
