If you just want to get to a class method from the instance, you can do
a.class.foo=3D10

Thanks I appreciate the quick reply, I think the () was a bit of
python showing its roots.
What I would like to do now is get instances of those classes and use =
the
methods that I've defined but I cant figure out how, without changing =
the class.

class A
  @@foo=3D1
  def self.foo=3D(n)
    @@foo =3D n
  end
end
puts "%s" % A.foo=3D10
a =3D A.new
#this does not work for an instance
#puts "%s" % a.foo=3D10
