Oh, I like this idiom, but strictly in stand-alone scripts. Bombing out of a program deep inside some library doesn't sit well with me.

And Perl exits with the following error message if the file doesn't exist using this idiom:
Can't open /does/not/exist: No such file or directory.
Uhm. I can do that :-)
