in reply to Completely Useless

Hey, you know what'd be neat? To customize the error message. Sure, it's still just as useless, but that's okay. So here's the new version:
package Silly::Die; use strict; use vars qw/$OUTPUT/; sub import { my $class = shift; my $caller = caller; no strict 'refs'; *{"${caller}::trying"} = \&{"${class}::trying"}; $OUTPUT = shift if @_ && ref $_[0] eq "CODE"; } sub trying { $OUTPUT ? $OUTPUT->($!) : $! } 1;
Usage is the same as before, but if you want an extra special output function, try this:
use Silly::Die sub { qq(I died with: "@_") }; open FILE, "foo" or die trying;
Prints:
I died with: "No such file or directory" at ./test.pl line 9.

[erix]: can you drop a name? :)
[karlgoethebier]: Corion: "...didn't leave business cards" Those guys came from Muränia?
[Corion]: karlgoethebier: Heh - naah, I think they are just very fresh out of university. At least they seem to have hired one person as key accountant who has done enterprise consulting etc. before :)
[Corion]: erix: It wouldn't be nice of me to publically shame and name ;)
[Corion]: I'm interested in how their product actually works. It uses websockets between two non-browser components, so there are some weird technology decisions, or rather, I assume the product started out as something completely different :)
[erix]: fair enough
