I hadn't thought of this so thanks for pointing it out. I'll give it a try 
and see how it works out. Incidently, by using function_name() in the 
override function I could detect whether the validate function is there or 
not, and it wouldn't be necessary to declare the validate function in each 
object. I still think my idea would be more convenient, but its probably too 
much work to implent to justify the benefits... One thing though, will 
overriding call_other also apply to the -> operator?
