I just wanted to clarify something. When I said there's no performance issue, I meant compared to calling the same number of non-recursive subs. Calling subs in general is an expensive operation in Perl, but that's not related to whether the sub is recursive or not.

So if you have no qualms with calling a sub seven times, you should have no qualms about calling a sub that recurses six times instead.
