I think you're mistaken. Try the following:
package My::Test;
sub new {
return bless {}, shift;
}
sub DESTROY {
warn "destroyed";
}
sub test {
my $object = new My::Test;
print ref $object, "\n";
# object will get destroyed when it goes out of scope (now)
}
for (1..10) {
warn "t $_\n";
test();
}
__END__
Your second example doesn't do what I think you were expecting.
