Hi --

After an earlier question (Mocking Class::DBI stringification) about Test::MockObject, I pushed on a bit and then encountered (to me) some extremely befuddling behavior.

In the code below, after I reset a variable, $id='apple', the mocking breaks.

Why?

Thanks --

use strict;
use warnings FATAL => 'all';
use Test::MockObject;
use Test::More tests => 7;
use Data::Dumper;
use UNIVERSAL qw (isa can);

package main;
my $id = -1;
sub return_id {return $id;}

package MockFoo;
# ! THIS IS THE *WRONG* WAY TO STRINGIFY A T:MO ??
use base qw(Test::MockObject);
use overload '""' => \&::return_id;

package main;
my $c = MockFoo->new;

$c->set_isa('Foo');
$c->mock('id',  \&::return_id);

is($id, -1, 'the bound scalar');
isa_ok($c, 'Foo');
ok ($c->isa('Foo'), 'and c isa foo, maybe');

ok(!isa($c,'Foo'), 'THIS SHOULD WORK (IMHO) but DOESNT, T:MO DOESNT FO
+OL UNIVERSAL');

ok(!can($c, 'id'), 'THIS SHOULD WORK (IMHO) but DOESNT, T:MO DOESNT FO
+OL UNIVERSAL');

is($c->id, -1, 'mocked accessor');
is($c->id, -1, 'mocked accessor repeated');
is('' . $c, -1, 'stringify');


$id='apple';
is($c->id, 'apple', 'apple:  mocked accessor');
is('' . $c, 'apple', 'apple: stringify');
