Hello,

I try to include some modules to a class instance, but I have  
problems with the scope, here's what I did:


person.roles.each do |role|
     class << person
         include role.class.const_get('Functions')
     end if role.class.const_defined?('Functions')
end unless person.nil?


As you can see role is not defined when I include it, does anybody  
know how I can add some singleton methods to person?

Regards
Florian
