Re: Best Practices for Exception Handling
in thread Best Practices for Exception Handling
There are problems when you mix the signal handling style with other modules that use exception handling, or use it in persistent environments like mod_perl so (in my opinion) it is best avoided.
Alternative Exception Handling Techniques in the mod_perl guide has more info on this. Also see the documentation on $^S (in perlvar) and die.
It's often simpler just to override CORE::GLOBAL::die and CORE::GLOBAL::warn.
