That's a good point. I should have specified printing to STDOUT. Even then there are things that could go wrong... someone could close STDOUT or select STDOUT to a file or something, but still, I think the clutter of testing every single print statement is a worse problem, in most cases, than an uncaught problem. Even if you catch the problem, what are you going to do about it? Write something to a logfile? If the disk is full you're still stuck.
