Class variables seem to trip up everyone learning Ruby, yet  
proficient Ruby programmers rarely seem to use them.  Are they really  
worth the trouble?  I've yet to feel the need to use them but maybe  
that is just me.

Any chance that class variables will disappear in Ruby 2.0?  I'm only  
half joking.
