Subject: Re: Newbie: how to dynamically add methods?

As far as I remember,
class_eval evaluates a block of code within the context of a class. So,
if you have a code which adds methods, they will be added to the class
and will be available to all instances of this class.

instance_eval is evaluated in the context of an object which is an
instance of some class. If you add methods they will be available only
to this object.
