Hi Monks, Is this possible? I have an object with a myList element. I would like to provide a client who uses the object the ability to use their own sorting routine. If they don't provide one, it fall backs to an internal sort routine. When I try to run my script, however, the fallback works as expected, but the $a and $b internal variables are undefined (they are not elements of $myList) in the client callback. Am I doing something wrong here or is this not possible? Thanks in advance. 
##Object:

sub _byCode {
   $a->asStringFmt() cmp $b->asStringFmt;
}

my $callback = $self->{sortCallback} || "_byCode";
...
foreach my $key (sort $callback @{$myList->getKeys}) {
...

}

##Client:

my $byCodeAndX = sub {
  ....
};

my $obj = new Obj( sortCallback => $byCodeAndX )
