Hi, I figured out what quote was actually doing. http://www.ccs.neu.edu/home/matthias/HtDP2e/i2-3.html explains it really well. "When ' encounters a plain piece of data--a number, a string, a Boolean, or an image--it disappears. When it sits in front of an open parenthesis, (, it inserts list to the right of the parenthesis and puts ' on all the items between ( and the closing )." So '(one two three) and (list 'one 'two 'three) are the same. '('one 'two 'three) would correspond to (list ''one ''two ''three).
Thanks for everyone who replied! Colin On Wed, Jan 29, 2014 at 11:00 PM, Colin Gan <[email protected]> wrote: > Hi people, > > The aforementioned s-exp produces the result (one two three).
