Does it need to be fixed? I don't think instance variables belong in
a Module, conceptually. They can be put there, yes, it's just harder
to get them in proper working order, which encourages 'proper' design
but allows circumvention if necessary. I can't think of any situations
where one would have no other option than instance variables in a
Module.

Veto CA Dream Act (free money to illegal alien students) signing is
still going...

if every CA citizens were present with Dream Act veto paper, I bet
that 60% will sign it. It only takes getting veto paper, pen and
personal signature. That's all to
take to repeal Dream Act crap. La Raza politicians came out this
bogus called Dream Act.
