I do also use a debugger, but lazily use print 
statements, too.  When I use the debugger (in
my case, in the IDE I use, Boa Constructor), I
do use break points and step through my code, 
but I have never used watches.  How do you use
them?

I think I was hoping for magic. :D

Would never have occurred to me.  That *is* odd!
