What's wrong with 
my $window;
for ($window = Gtk2::Window->new( "toplevel" )) {
    $_->signal_connect( delete_event => sub { Gtk2->main_quit } );
    $_->set_title( "Test" );
    $_->set_border_width( 15 );
    $_->add( do {
        my $button = Gtk2::Button->new( "Quit" );
        $button->signal_connect( clicked => sub { Gtk2->main_quit } );
        $button;
    } );
    $_->show_all();
}

$_ is the "current topic" and for() acts as a topicalizer. Unless, of course, I'm missing something ...

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
