I've been using IO::All
for a few months now and I am now sure that it is the best thing since sliced bread. In fact it *is* sliced bread. It takes care of all the common niggliness that makes I/O such a pain in the anatomical part of your choice, wrapping it up in a neat, easy to use package. It does for I/O what Perl itself has done for data manipulation. It makes it painless so that for many, many applications you can let it worry about the vagaries of the systems requirements, error checking, etc. while you worry only about your algorithms. I think it should be distributed as a core module with Perl (It's not already, is it?).
P.S. No, Brian Ingerson didn't pay me to say that, and I'm not married to his sister.
