what type of dsc is this

[navalned]

I'm playing around with Gtk2 and I have the following output from a Data::Dumper.
I'm not 100% sure what its telling me, so its hard to move forward. My best guess is
an array of blessed hashes, but again not sure.
Thanks in advance.

$VAR1 = [bless( {}, 'Gtk2::Window' ),bless( {}, 'Gtk2::Window' ),bless( {}, 'Gtk2::Window' )];
