This reminded me very much of an article I read recently.  After some searching, I 
was able to relocate the article.  It is entitled "A Modular Framework for 
Artificial Intelligence Based on Stimulus Response Directives," and was written by 
Charles Guy.

I wondered whether or not you were familiar with the article.  I found it 
fascinating.

Also, what happens if this.room.contains(objtype(really_cute_rat)) /*OK...this is 
hypothetical*/ and this.room.contains(objtype(hunk_of_cheese)) and rats_feed and 
rats_reproduce are at the exact same priority level?  Will this lead to a 
Capt-Kirk-like logic problem in which rats_self_destruct is initiated?  Just 
wondering.
