Subject: Inheritance problem with dynamic methods

Hello,

I'm tying to create a method which would allow me to get and set
instance variables having the same name as the class. And this should be
true even for classes inheriting it.

For instance

[code]
class Mother
         define_method(self.to_s.downcase){ instance_variable_get
'@'<<self.class.to_s.downcase }
         define_method((self.to_s.downcase+'=').to_sym){|nom|
instance_variable_set '@'<<self.class.to_s.downcase, nom}
end
class Daughter < Mother
end
[/code]

At the moment, this code creates "mother" and "mother=" instance methods
for both Mother and Daughter's classes.
Instead, what I'd like to have in a "mother" and "mother=" instance
methods for Mother, and "daughter" and "daughter=" for Daughter.

I think that there is some meta programming trick that I'm missing but I
can't find which one.

Could you help me?
