Re: Tail Recursion "Optimising" with goto &sub

This is a pretty elaborate way to do it, but it's good to see a demonstration of perl's unapologetic form of goto outside AUTOLOAD subs.

Have you benchmarked this against a straight iterative implementation?

No, I haven't benchmarked it yet. I'm curious about the results vs normal recursion but surely the straight iterative version would be faster. Only if you were using a very functional style would this potentially be a useful place to look for speed, but in that case you'd probably want to do it in the compiler/optimizer rather than by hand.
