[plt-scheme] Re: Scheme workshop survey

Alan, Marc didn't ask for us to evaluate the thing, which in any case  
is Scheme-specific silliness. He asked what is the value of (car ...)  
and the value -- as opposed to what you see on the screen -- is  
definitely '(a b c). After all, it is possible to take the car of  
that value again, yet one thing you wouldn't want to do is to run  
(car (a b c)) because that goes nowhere.

Lispers and Schemers have failed to really articulate semantics  
properly for a long time now. Read Wadler's Calculating is better  
than Scheming. He's right.
