Subject: Delegating class methods

Hi all,

how would you forward calls from class methods to a class atribute?
Like in:

class Foo
  @@hash = {}

  def self.size
    @@hash.size
  end
end

I have to delegate a fairly large number of calls to an attribute. I'm
currently using method_missing, but I was wondering if there was a
cleaner way to do that as the method names are known at load time. I
didn't find any using the standard library. Perhaps using some
metaprogramming.

Thanks!
