- * Apply a visitor to an AST node or document.
- *
- * Walks through the tree (depth-first) starting from `node`, calling a
- * `visitor` function with three arguments:
- * - `key`: For sequence values and map `Pair`, the node's index in the
- * collection. Within a `Pair`, `'key'` or `'value'`, correspondingly.
- * `null` for the root node.
- * - `node`: The current node.
- * - `path`: The ancestry of the current node.
- *
- * The return value of the visitor may be used to control the traversal:
- * - `undefined` (default): Do nothing and continue
- * - `visit.SKIP`: Do not visit the children of this node, continue with next
- * sibling
- * - `visit.BREAK`: Terminate traversal completely
- * - `visit.REMOVE`: Remove the current node, then continue with the next one
- * - `Node`: Replace the current node, then continue by visiting it
- * - `number`: While iterating the items of a sequence or map, set the index
- * of the next step. This is useful especially if the index of the current
- * node has changed.
- *
- * If `visitor` is a single function, it will be called with all values
- * encountered in the tree, including e.g. `null` values. Alternatively,
- * separate visitor functions may be defined for each `Map`, `Pair`, `Seq`,
- * `Alias` and `Scalar` node. To define the same visitor function for more than
- * one node type, use the `Collection` (map and seq), `Value` (map, seq & scalar)
- * and `Node` (alias, map, seq & scalar) targets. Of all these, only the most
- * specific defined one will be used for each node.
