Maybe, but that's a lot of optimization for a little problem.  These  
four active record methods (table_name, primary_key, etc.) can't be  
called so often that it becomes necessary to avoid the cost of  
dereferencing a variable.

There's an article by _why the lucky stiff_ (http:// 
whytheluckystiff.net/articles/seeingMetaclassesClearly.html) that  
gets tantalizingly close to answering this question, but not close  
enough.  At least not for me.  _why, are you lurking?  Any input?

I dunno, maybe I'm looking for something that's not there, but I'd  
love to keep the discussion going for a bit, if I may.
