Detailed Description

A utility result that is used to signal how to proceed with an ongoing walk:

• Interrupt: the walk will be interrupted and no more operations, regions or blocks will be visited.
• Advance: the walk will continue.
• Skip: the walk of the current operation, region or block and their nested elements that haven't been visited already will be skipped and will continue with the next operation, region or block.
