}Almost every exercise I've had a problem with has been of the even numbered variety - are there only answers to the odd-numbered ones? If so thats... somewhat vexing to put it mildly.
Steve, you should be writing an updated edition or a supplement (if even on lulu.com) to take into consideration the updates to the language (and IDE).
I am sure many of us would be happy to even pre-order your book!
