Is it correct to say that class variables '@@' are similar to globals in
that they are global to their class?

Their class, and subclasses of their class. They're pretty
global-ish. That's scheduled to be fixed^H^H^H^H^H^H^Hchange in Ruby
2.0, when they'll be visible only to their class/module and the
instance methods inside it (as I understand Matz's description).

OK, thanks... about the time I fully understand it... things will
probably change

Any sense of when 2.0 might be released?
