In fact it is good recursive code, mathematically speaking. It's just that some compilers are bad at it aka doing brute force instead of tail recursion. The main selling point of these "interpreted" languages is the programmer productivity. Now why the hell one would have to write more complicated algorithms just to go around the compiler? C does this just fine. The 0.6 seconds to 5 minutes difference for the same simple algorithm shows that something is fundamentally broken.

I do write recursive code. However, I certainly do my best not to write bad recursive code...
