I am getting an error, and am finding it difficult to ascertain the exact reason why the error is being logged.
(The whole script is CARP'd)

error:
Sort subroutine didn't return single value.
script.pl died with a software error

Code snippet: 

my $messages = get_arrayref_of_objects;

eval { $messages = [ sort { $a=>rank <=> $b->rank } @$messages ]; }; #
+ EVAL1
$LOG_OB->warning( "Sort failed: $@" );

foreach my $message (@$messages)
{
   eval { $message->do_some_method; }; #EVAL2
   # <1>
   if ($@)
   {
      $LOG_OB->fatal( "YOIKES: $@" );
   }
}

Now I know that the sort (at EVAL1)is failing, because the 'rank' method does not exist on the 'message' object.

But why is the sort failure logging this error?
Is $@ still defined at <1> even though the previous eval has no problems (EVAL2 never fails)?
Or is it something completely different and I am barking up the wrong tree?

In reply to Perl behaviour - is it '$@' or 'sort' causing me grief? by graq
