 eval is evil, and it's still exist a stupid way to write it :-)

pigeon% cat b.rb
#!/usr/bin/ruby
module Hab
   module Tmp
      def defin(a)
         attr_accessor a
      end
   end

   def self.append_features(c)
      super
      c.extend Tmp
   end

   def biv(attributes)
      attributes.each do |k, v|
         type.send(:defin, k)
         send(k.to_s + "=", v)
      end
   end

end

class A
   include Hab
end

a = A.new
a.biv("aaa" => [1, 2], :bbb => [3, 4])
p a.aaa
p a.bbb

pigeon% b.rb
