Subject: About <programming ruby, 2nc edition>, meta class and Class



General speaking, it’s about the relationship between virtual 
class(metaclass ) and Class.

It’s all in chapter 24.
In Figure 24.2, Dave gives the relationship between object 
instance(a_guitar), its class(Guitar) and its metaclass(Guitar`). .
Then in section “Class and Module Definitions” , as we see in the code 
example, any class (for example, class Test) is a object instance of 
class Class.
So I think Class is a metaclass of any class. Since Guitar` is a 
metaclass of Guitar, can I think Guitar` is a subclass of Class. If my 
understanding is right, I think it’s better Dave can add this 
relationship in Figure 24.2 and make it clearer.

Thanks in advance
