That's even better zimbatm. Ops, I was tempted to write super.columns again :)

Woops, hope this one is better (what formatting do you use ?) :

irb(main):001:0> class User
irb(main):002:1>   def self.columns
irb(main):003:2>     "name,email"
irb(main):004:2>     end
irb(main):005:1>   end
=> nil
irb(main):006:0> class Customer < User
irb(main):007:1>   def self.columns
irb(main):008:2>     super + ",saldo"
irb(main):009:2>     end
irb(main):010:1>   end
=> nil
irb(main):011:0> Customer.columns
=> "name,email,saldo"

It could also be written like that : irb(main):001:0> class User irb(main):002:1> def self.columns irb(main):003:2> "name,email" irb(main):004:2> end irb(main):005:1> end => nil irb(main):006:0> class Customer < User irb(main):007:1> def self.columns irb(main):008:2> super + ",saldo" irb(main):009:2> end irb(main):010:1> end => nil irb(main):011:0> Customer.columns => "name,email,saldo"
