i originally didn't like the warn on errors stuff either, but i haven't come
to think that it was without much question the best route.

as was discussed way back when the original discussion came to a close the
following will achieve the other desired behavior (dying on all errors.)

  Glib->install_exception_handler (sub {
                warn shift;
                exit;
        });

so there's really no point in complaining about the choice. if you don't like
it all it takes is 4 lines of code and it won't work that way.

an example showing the behavior:
******************************************
#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;
use Glib;

Glib->install_exception_handler (sub {
                warn shift;
                exit;
        });

my $loop = Glib::MainLoop->new;

Glib::Timeout->add (1000, sub {
                $loop->foo_bar;
                1;
        });

$loop->run;
