I disagree.  The current behavior is the more general one, and 
typically, that general info _is_ something you want to see. Well, let 
me withdraw my assertion about "you"; it's something that _I_ want to 

Also, if you really want to see the datum form, and you're doing it 
enough times to be agitated about the overhead of clicking of the 
triangle, why not just wrap the expression you want to expand in 
(syntax-object->datum (expand ...)) and be done with it?


p.s.: handy tip that took me too long to figure out: if what you want 
is to see the expansion of the thing in beginner language, you can just 
wrap the syntax you're interested in with a (module foo (lib 
"htdp-beginner.ss" "lang") ...) .  Apologies if you already knew that.
