Best error handling mechanism?

[Rob Hoelz]

I've read numerous articles on the internet, and I haven't come to a
clear conclusion yet: What form of error handling is best in Perl?
I've seen try/catch with Error.pm, eval/die with Exception.pm, and just
plain old eval/die. What's the best way to go about creating a robust
error handler?

Thanks,
Rob

There is no best way.

You haven't even hinted at what kind of project you need error handling
for. It takes intimate knowledge about a project and its surrounding
conditions to make an informed decision about a detail like that.

There is a chapter (or section) about error handling in _Perl Best
Practices_ by Damian Conway. I'd take a look at that for general
points of view. Otherwise, you'll have to do what everybody has to
do: Evaluate the options, identify their advantages and disadvantages
in relation to the project and take a pick.

If that's too tedious (it is tedious) just take a pick and hope for the
best.

The best way is not to make errors at all. Corporate policies should
always include a clause to that effect.
