* Indicate that a CustomStringCallback can return undefined to indicate that no custom behavior should be applied for that node. * Allow WalkCallback to return false. Otherwise, a callback that may or may not prevent further traversal can't be expressed in TypeScript, since it doesn't allow a function to only return a value some of the time.
