Well I'm feeling amiably disagreeable too, so I'll differ with that. 
A "dictionary" in the wider-than-Python sense has an ordering 
to it that is based on it's keys. The order of arguments to a 
function is _not_ an ordering based on the argument names; 
ergo, the existence of an American Heritage Dictionary gets 
you no closer to your goal (in this sense, at least). What 
you're apparently arguing for is an ordered dictionary. What 
you _want_ is an indexed list.
