Tail recursion has a seldom-noted cost. Sure, it speeds up some recursive code. But it also means that if you get into trouble, a stack backtrace will be missing a lot of potentially useful context.

That said, you can manually do tail-recursion in Perl with goto. Unfortunately it is not as efficient as it should be, and I'm not entirely sure why.
