You could leave out the "class_eval" and "define_method" and simply
write "def initialize ... end" like you normally do, since this isn't a
dynamic method definition at all:
def initialize
self.class.traits.each do |k,v|

end
end

This is a misunderstanding. Every object *has* a class, which defines
the methods of the object. You can interpret classes as some kind of
"construction plans" for objects.
In most object oriented languages like Java or C++., classes aren't
objects themselves but rather some kind of special entities. This isn't
true for Ruby. In Ruby, classes are normal objects that behave like any
other object. They can have instance variables and methods (like for
example "superclass" or "attr_accessor").
The class of every class is "Class".
> If "hello" is an instance and String is a class, what is an example of

Both "hello" and String are objects. "hello" is an instance of the class
String, and String is an instance of the class Class.
