This seems to do the trick: 
my @array = (
    'Main//News',
    'Main//Reviews//PC',
    'Main//Reviews//PS2',
    'Main//Reviews//XBox',
    'Other Menu//Other//Sub//Menus'
);

sub menu
{
$_=q~;ir$w}Uw&Ii,jmcumUumbo#e_cjm>oImb}U|nyp@''@#l"ynrjmUtthU]h!U[$rhb

}

print menu(sort@array),$/;

If you don't pass in a sorted array, it can create strange menus. It's also easily confused by similar leaf nodes.
