<sigh> you're right -- we didn't test *all* of the code as printed (the
shame...).  I _hope_ the zip you can download from O'Reilly's site with
all the fixes is better (that one is also easier for us to fix if and when
such small errors come to light).

I wouldn't be quite as confident (haven't been on the site in earnest for
a while, so i don't know if Activestate's been doing any fixing, though).

Indeed.  Any such mistake we learn about, we can most easily fix in
a second printing (if the book is as successful as your imagination makes
it, there will be a second printing...)... it's even faster and easier to 
correct them in the scripts' zipfile...

Thanks!  But I _do_ feel guilty about any error that may have
slipped by...:-(.  I hope we can fix any such error ASAP...!!!
