AppConfig loading undef values into ARGCOUNT_LIST ksdoctor 03-22-2007

What is the syntax for loading empty (undef) or empty strings into an
AppConfig value set to ARGCOUNT_LIST ?

I am using AppConfig 1.56

Here is a code snippet:
use AppConfig;
my $config = AppConfig->new();

$config->define("Thing=s@");
$config->file("config.txt");

print join("\n", @) . "\n";

--- config.txt---

Thing = 'one'
Thing = ''
Thing = 'three'
Thing = <undef>
Thing = undef

---

The result is only
STDERR : "Thing expects an argument at ./config.txt line 2
STDOUT :
one
<undef>
undef

I would like AppConfig to add an undef or empty string to the list
rather than ignore it.

thanks,
-K S D

I haven't found a way to do this either. I just clear the entry
manually. A better way may be to define a "VAR IS NULL" line, which
would set VAR to undef. But I don't know who's maintaining AppConfig
these days; I asked some questions a year ago and never heard back.
