It's not needed. It's probably code that was originally written as
my $q = new CGI;
sub popup_menu_factory { my @tmp = @_; sub { $q->popup_menu(@tmp) }}
This meaning that we get closure like behavior, do you could do
my $popup = popup_menu_factory(@arguments);
...later...
print $popup->() . " select an option " . $popup->();
Later.
