Aside from the fact that the approach given in your reply is 'cleaner' and therefore, to my mind, preferable to something like 
sub foo {
    my $shared_with_all_recur = ...;

    my $_recur;
    $_recur = sub {
        ...
        $_recur->(...);
        ...
    };

    $_recur->(...);
}

is there any advantage to using a localized glob rather than a lexical scalar?
