Perl's Warn and Die Signals
This is a tutorial on using Perl's warn and die signals. It is based on a post I made some time ago, here, but covers more of the details and raises more of the pitfalls. In this tutorial I attempt to separate the warn and die signals from the OS signals, explain how they are used and what they can be used for, and explore the problems that can come up.
