Well, I thought we were talking about classes which contain only class 
methods and class data (which are currently called 'singletons').  But, 
in C# or C++ these are called 'static classes.'  I guess that makes 
sense for them because the code itself can never change or be enhanced 
(like it can be in Ruby).

Ok.  That's what I meant by metaprogramming.  I wasn't aware of the 
scope issue though.  Also, what do you mean by 'their methods may modify 
any instances'?

But, yea, given the 'dynamic' nature of Ruby, it doesn't make sense to 
say something is static.
