I chuckled. I think OP and others in the thread completely missed the point. If you use a language with references, you're using pointers. I never said pointer arithmetic, dereferencing etc. Same with recursion. Yeah, implementing recursive calls in a language like Java is dumb. But tail recursion isn't. Nor is using an equivalent of a recursive algorithm using a stack or queue. If you don't think about these things, or don't know whether you do... you may be writing PHP
