Indeed, I like the look of that. I imagine, however, he added the _a 
because he didn't want to crowd the method namespace (I assume the same 
reason he changed id to object_id).

I can see that. I guess it's just that I'm not used to thinking of 
instances as "kinds." Also "kind of" comes off sounding like 
"approximately," which is kind of weird. I'm obviously too closed-minded 
for Ruby. :)
