I have no idea, you might ask at ruby-core. But there is quite a
consensus not to use them. What is your use case?
As much as I can guess from your example code, class instance
variables should do the trick for you.

e.g.

module A
   class << self
     attr_accessor :a
   end
end

I'm not against types, but I don't know of any type systems that
aren't a complete pain, so I still like dynamic typing.
