What's wrong with cutting and pasting a relevant portion of the documentation that might help the OP? Even though I didn't explain it, I think it can still be quite helpful. Maybe I'm wrong, but I consider perldiag one of the oft-overlooked parts of the Perl documentation, therefore I don't assume someone has looked there when they post something like 'Why am I getting this error?' And why should I just post 'see perldoc perldiag' when I can just as easily snip the relevant chunk of a lengthy (3910 lines on my box) perldoc? Is PM screen real-estate so precious?
