A New Control Flow Construct for Tree Traversal

This article proposes a new control flow construct called `for_tree` designed to simplify tree traversal. Compared to traditional recursive functions, `for_tree` offers improved readability and maintainability, supporting operations like `break`, `continue`, and `prune`. The author provides a C++ implementation as a proof of concept, showcasing its flexibility in traversing various tree structures, including in-memory trees and trees generated on the fly. The `for_tree` construct is presented as a more efficient and less error-prone alternative to recursive functions for tree traversal.
