Hi,

I'm using a hash whose keys store object references. Can I simply delete that key or do I need to undef the object reference to make sure the objects are garbage collected? The hash stays in scope but the object was declared lexically scoped earlier in a subroutine and assigned to the value of a hash: 

use Foo::Object;
my %hash = ();

&somesub;

# does this garbage collect the object?
delete $hash{'object'} if exists $hash{'object'}

sub somesub {
    $hash{'object'}=new Foo::Object;
}

Is there anything that I would need to specifically undef before deleting such a key? Are there other issues here, or am I just confused?

Thanks.
