In order to support fields of the same name in subclasses we are now prefixing them with name of the class that defines them. To provide convenient way to access them from generated bytecode and also directly from JavaScript, there is a getter/setter function for each field. It starts with _ followed by the field name. If called with a parameter, it sets the field, with a parameter it just returns it.
