The alternative would be to use @n, but I am not sure that Struct organises these properties around individual instance variable. it probably keeps them in an internal hash, so you have to use the accessor 'n'. However, when you use it on the left handside you must prefix with self, otherwise ruby thinks it is a variable n, rather than a call to the attribute writer 'n='. I am not sure if this is supposed to be a bug.. it's certainly a surprising behaviour. -- -- Chiaroscuro -- Liquid Development Blog: http://feeds.feedburner.com/blogspot/liquiddevelopment
