No, that doesn't work. 

{
    package Foo;
    use overload '""' => sub { 'Bar' };
    sub new { bless({}, shift) }
}

{
    my $value = Foo->new;

    # We want the true type of blessed objects like XML::DOM::Document
    my $true_type;
    if(ref($value)) {
        $true_type = scalar($value);
        $true_type =~ s/.*=(\w*).*/$1/;
        }
    print ref($value)," is really an $true_type\n";
}

Foo is really an Bar

But it's really a hash.

Scalar::Util's blessed, reftype and refaddr provide the desired $class, $type and $addr respectively.
