By wrapping the potentially failing code up in an eval you can die and report errors back that way. Consider:
use strict;
use warnings;
my (%Numbers,$i);
my @Values = qw/first second third/;
$Numbers{$_} = ++$i for @Values;
for my $cur (@Values) {
next if eval {
my $value = &get_number ($cur);
$value .= &get_ordinal ($cur);
# more, more..
print "$cur is $value\n";
};
print $@;
}
sub get_number
{
my $value = shift;
if ($value eq "second") {
die "bad value";
}
return $Numbers{$value};
}
sub get_ordinal
{
return substr(shift, -2);
}
Prints:
first is 1st
bad value at noname.pl line 25.
third is 3rd
