But then do students try to use that in the playground? Maybe instance-side comments should have no pseudo variable, and use the class directly. After all, comments have an absolute position in the hierarchy. Its not like you can evaluate the comment from a subclass. On class-side "self" seems okay in comments, since it means the same thing as in code. Perhaps it even draws attention of students that the class is itself an object. cheers -ben > > > > Hi all, > > in Nautilus, `self` is always the current class instance.
