Many non-recursive solutions have a significant (often buggy) overhead in achieving the same as the mechanism of preserving the variables on that call stack level. If you find yourself in doing just that, you have to wonder if a recursive soltuion would make sense.

Walter,

Exactly. For example, the non-recursive search I posted earlier could be done recursively. What's the point, however?
