Dear Monks,

I'm obviously missing something very simple when it comes to using the automated coersion mechanism with Class::Std.

Here is my simple class ...

package BaseClass;
use Class::Std;
{
    sub as_num :NUMERIFY  { return 42 }
#    sub as_num { return 42 }
#    use overload (q{0+} => 'as_num', fallback=>1);
    1;
}

Here is my calling code ...

#!/usr/bin/perl

use strict;
use warnings;

use BaseClass ;
my $c = BaseClass->new ;
my $x = 0 ;
$x += $c ;
print "x = $x\n";

And here is what I get when I run it ...

[stbaldwin@audev02 dev]$ ./tst.pl
Use of uninitialized value in method lookup at (eval 2) line 3.
Can't locate object method "" via package "BaseClass" at (eval 2) line
+ 3

As you can see, I have also experimented with using overload, and that mechanism works fine. However, call me stubborn, but I like to understand the tools I use.

Any help is much appreciated. Thanks.
