Hi,

What is called the process of adding a new method of an already defined class ?

For example:

class A
   def a
   end
end

And in another file:

class A
   def b
   end
end

And now my real question:

What if I want to declare a new class variable in the initialize method ?
If it's a derived class I can call super:
def initialize
   super
   @my_var = ""
end

but if it not derived ?
How can I do this ?

Thanks,
Mickael
