Subject: question on Struct and class_eval

Hello

I have this code:

country = Struct.new("france".intern, :person)
person_class = Struct.new("person".intern)

                     
meth = <<-METHOD
    def method
       @person = @person_class.new
    end
    METHOD
         
country.class_eval(meth)

c = country.new()
c.method()


this is my error message:
../temp.rb
(eval):2: warning: instance variable @person_class not initialized
(eval):2:in `method': undefined method `new' for nil (NoMethodError)
        from ./temp.rb:17


the one that bothers me is the first one with "@person_class not 
initialized"

is it possible to do this ?? I am not sure if this could work at all.
I also tried
"@person_class.name" + ".new"

but @person_class.name does return an empty string.

any ideas

Thanks in advance

Markus
