Re: Error Handling Misconception

[gjb]

To catch die's with eval, the eval block must be terminated with a semi-colon.
So you'd better be off rewriting the while as

for (;;) {
  my $value = eval { $object->next_val() };
  if ($@) {
    print "Error: $@\n";
    next;
  }
  last unless $value;
  # do something useful...
}

Hope this helps, -gjb-

Update: Althought chromatic puts it very politely, he's dead right: the semi-colon stuff above was nonsense. Thanks chromatic for making me think twice.

Do you have a source for this?

sub dies
{
    die "That's it!";
}

if (eval { dies(); 1 })
{
    print "No death!\n";
}
else
{
    print "Death caught: $@\n";
}

You probably got that idea about the semi-colon from the Error module which uses sub refs to implement a try/catch syntax. The sub refs do require a semi-colon.
