YAML and class variables

[Rick Ashton]

Hi

When an object's .to_yaml method is used, class variables aren't
recorded. This makes sense, I guess, but how can someone then serialize
a class variable and restore it later?

Thanks!

You don't. Basically a class variable belongs to the class and that's
typically not created via some serialization mechanism (yaml, marshal)
but through code. Apart from that class variables have a whole bunch of
problems of their own so you better avoid them anyway. My 0.02 EUR...

Kind regards
